What’s new in Angular JS 6?

One of the most popular frameworks in the web development space are Angular JS. The framework’s latest version Angular JS 6 was released in April. This was the biggest release by Google this year. This has benefited the entire community, particularly Angular JS classes in Pune, who provide training to aspiring software programs. This rollout consists of many new features and important upgrades. The new features will certainly be a great value addition to every software developer. Training centers providing Angular JS courses in Pune are absolutely ga-ga over these new enhancements in the framework.

The new release confirms that the latest version of Angular JS is extremely light, fast and very easy to use. This is a boon to the developer community as it makes their life easier. Training centers who providing Angular JS coaching in Pune have already started empowering the developers with this latest version of Angular JS. The new version supports TypeScript version 2.7, which makes coding easier along with conditional type declarations, default declarations and strict class declarations. Angular JS coaching classes have already started extensively training their students on the new version and this framework is particularly popular among renowned Angular JS training in Pune and also private Angular JS classes in Pune. Today, there are many institutes such as Cyber Success, that provide Angular JS certification in Pune.

However, let us have a look at some of the salient features of Angular JS.

1.    Elements

This is a perfect framework for developers who want to develop single page applications. Moreover, it was a very tedious task to create widgets on an existing page. However, with the new Angular JS 6, the same activity can be performed using Angular Elements. The ability of elements is to create a component and then publish the component as a web component, which can be further used in an HTML page.

2.    Service Workers

Service workers are typically scripts that function in a browser and these workers manage to cache an application. This feature was earlier introduced in Angular 5. However, the latest version has some bug fixes and new functionalities. So, if you are planning to install the new version, then the previous or existing service workers have to be uninstalled. There was no direct method of doing this in Angular 5, but in Angular 6, you can do it by running the script file, safety-worker.js, which is usually a part of the production bundle.

3.    No more template elements

The concept of template element diminished when Angular 4 was launched. However, with Angular 6, this component has been totally eliminated. This is replaced by <ng-template>

4.    i18n

This is one of the major changes in the new version of Angular JS 6. Internationalization of i18n that comes with a run time rendering does not require anyone to build one application per locale. There has been a change in the currency pipe as well so it does not round up every currency value with 2 digits.

5.    Ivy

The team at Angular has introduced its third rendering engine, which is called Ivy. Ivy is said to be the next generation Angular rendering engine. Some of the previous versions of Angular had view engine, which was used for rendering purpose. This new rendering engine

helps in increasing speed and reduces the size of the application overall.

Over and above these primary features and improvements, the new Angular JS version 6 has few other elements that the team has incorporated, viz:-

a.    ngModelChange

b.    ElementRef<T>

c.    Bazel Compiler

d.    RxJS 6.0

e.    Tree Shaking

At Cyber Success, we are constantly endeavoring to provide Best angularjs training in Pune across the latest technology stack and other tools to help the industry with the best software programmers. This new enhancement has really helped us in enhancing the skill set of Angular JS developers and we constantly strive to provide the best-in-class resources for our clients.

Top Java Interview Questions and Answers

1. What is JDK?

Ans: JDK is an acronym for Java Development Kit. It is a bundle of software components that is used to develop Java-based applications includes JRE and the compilers and tools (like JavaDoc, and Java Debugger) to create and compile programs.

2. Which is the latest Version of Java?

Ans:  Java SE 12  release date 2019-03-19,  feature contains Initial release

Java SE 12.0.1 release date 2019-04-16, feature contains New Japanese Era Name & Security fixes

3. How can you access the static global variable of a class?

Ans: You need an extern keyword.
For example, we have one global variable named an in main.cpp

1. // main.cpp
2. int a = 1;
3. int main()
4. {
5. // do something...
6. }
7.  

We want to access the global variable an in MyClass.cpp, we should use extern.

1. // MyClass.cpp
2. extern int a;
3.  
4. MyClass::MyClass()
5. {
6. a = 3; // Change the global variable
7. }

4. What is Diamond Problem?

Ans: The diamond problem refers to an ambiguity that brews due to allowing multiple inheritance. In Java, multiple inheritance is not allowed for classes and permitted only for interfaces to eliminates this serious issue.

5. When IIB's will be executed?

Ans: IIBs are executed before constructors. They run each time when the object of the class is created.

6. What is the rule to be followed by the sub-class of an abstract class?

Ans:

1. An abstract class must be declared with an abstract keyword.
2. It can have abstract and non-abstract methods.
3. It cannot be instantiated.
4. It can have constructors and static methods also.
5. It can have final methods which will force the subclass not to change the body of the method.

7. What does a method's return type signify?

Ans: Return is a reserved keyword in Java i.e, we can’t use it as an identifier. It is used to exit from a method, with or without a value.

Return can be used with methods in two ways:

1. Methods returning a value: For methods that define a return type, the return statement must be immediately followed by the return value.
2. Methods not returning a value: For methods that don’t return a value, the return statement can be skipped.

8. Recursion while constructor overloading will result in compile time or run time error

Ans: Run time error

9. What is Auto Upcasting and Explicit Downcasting?

Ans: Converting a subclass type to a superclass type is known as up casting.

Example-

class Super {

   void Sample() {

      System.out.println("method of super class");

   }

}

public class Sub extends Super {

   void Sample() {

      System.out.println("method of sub class");

   }

   public static void main(String args[]) {

      Super obj =(Super) new Sub(); obj.Sample();

   }

}

Converting a superclass type to a subclass type is known as downcasting.

Example-

class Super {

   void Sample() {

      System.out.println("method of super class");

   }

}

public class Sub extends Super {

   void Sample() {

      System.out.println("method of sub class");

   }

   public static void main(String args[]) {

      Super obj = new Sub();

      Sub sub = (Sub) obj; sub.Sample();

   }

}

10. What is JRE?

Ans: JRE stands for “Java Runtime Environment” and may also be written as “Java RTE.” The Java Runtime Environment provides the minimum requirements for executing a Java application; it consists of the Java Virtual Machine (JVM), core classes, and supporting files.

Why learning python is must to become a data scientist?

Data Science is one of the buzzwords that have been traveling across the world for years. Many Python classes in Pune are focusing on this field as the demand by the industry leading to a hike in demand by both experienced as well as fresher’s across the globe. Many articles and surveys show that Data science is the #1 job in countries like America. Before joining any Python course in Pune, students often seek for approaches to Data science via Python.

Data science is a trending field because of the paradigm shifts in the approach towards the customer by industries across the world. The amount of Data being generated every day is over 2.5 Quintillion bytes and it needs to be processed for proper use. Data scientist, based on the type of industry, usually analyses the data to either meet some specific business model or reach a goal. R, MATLAB, SQL, Java, C/C++ are languages being used for applying Data science algorithms led by Python. Let’s discuss some details regarding why python is a must if you want to learn data science:

Python is a powerful yet simple tool: Python is a flexible, open source and free to use language. With it’s easy to read and understandable syntax, python is ruling the software industry with it’s simple yet unique features. Many programmers start with learning python language due to the mentioned reason. Applying various algorithms is simple in Python and this is a mainstream reason why python has developed so much and why it is in demand by the IT industry.

Data Science is considered an exciting job and is one of the highest paid jobs in the world due to its modesty. And python has already stripped all other languages in terms of expandability and popularity. It has become the fastest growing language according to stack overflow. The next year, 2020, will probably mark the total rule of python in the fields of Data Science and Artificial intelligence.

R vs. Python: It is true that there was a time when the whole Data science workload was ruled by the language R and many small companies are still using it due to its specific approach to Data analysis. I was learning R myself to kick-start my career in Data science before an experienced machine learning expert from IBM asked me to move to Python for Data science. With the integration of Agile and DevOps methodologies of development by industries across the world, swiftness, easiness, and inter-dependence have been a crucial factor. And python check marks all the point of being versatile language.

Python libraries: This is the most important aspect why Python is more demanded by the industry than R. Apart from being a simple python has a lot of libraries, packages, and resources which makes it even easier to implement algorithms and analytical compositions over the Data being generated. Packages like PyBrain and PyMySQL are used to integrate and use other language features in a simpler way while being able to use powerful libraries from the Python resources. Some of the important Data science libraries in python are Numpy(for enhanced scientific computing), Matplotlib and SeaBorn(for visualization of Data), Scikit learn(a package containing various easy-to-use machine learning algorithms for data analysis and mining) and Pandas (for manipulation and analysis of data).

Apart from the set of potent libraries, implementation and analysis with python becomes easy because scripting can be done to automate many pre-processing methods, which are universal to all the data being analyzed. Also, you can adapt these with web development and many other implementations of Python like game development to strengthen other applications as well.

From healthcare and Finance to entertainment and Social media, Data science is a field, currently being demanded by almost all the industries. Although tech giants are looking for experienced professionals for their Data science teams, due to blooming start-up and freelance culture, the scope for freshers has never become less widened.

If you’re looking for a Data Science course, many online portals are available. But many of you might believe in practically real-time training by professionals. Learning python with Cyber Success Python coaching in Pune can help you kickstart your journey as a Data scientist by introducing and helping you learn and understand the use of Data science libraries in Python.

The path to being a successful Data scientist is based on the type of industry you want to work for, but surely getting yourself certified from a reputed Python institute in Pune is where you should start. The good news is you can still catch-up to learn the skills recognized in a mature data scientist as the job profile is dependent on various aspects of the business motives of industry project  you are working for. With utmost the best Python classes in Pune, Cybersuccess, you can give a push to your passion towards Data and kickstart the journey towards Data science.
