Why is Java so important?

Java was designed to be easy to use and is therefore easy to write, compile, debug, and learn than other programming languages. Java is object-oriented. This allows you to create modular programs and reusable code. Java is platform-independent.

Why Java is very secure?

Because Java compiles as bytecode which then runs inside a Virtual machine, it cannot access the computer it runs on like a natively compiled program can. The general reason why Java is considered to be more secure than, say C, is because it handles memory management for you.

How can Java change your life?

Write better code: The Java programming language encourages good coding practices, and automatic garbage collection helps you avoid memory leaks. Its object orientation, its JavaBeans™ component architecture, and its wide-ranging, easily extendible API let you reuse existing, tested code and introduce fewer bugs.

What is Java best used for?

One of the most widely used programming languages, Java is used as the server-side language for most back-end development projects, including those involving big data and Android development. Java is also commonly used for desktop computing, other mobile computing, games, and numerical computing.

Why do you like Java?

Java has powerful development tools like Eclipse and Net-Beans that have played a vital role in making Java as one of the best programming language. You would love coding in the Integrated Development Environment especially if you have been using notepad, etc. It makes the development much faster, easier and fluent.

Why Java is a simple language?

Java is simple because: Its coding style is very clean and easy to understand. It removes complexity because it doesn’t use complex and difficult features of other languages like C and C++, which are as follows: Concept of Explicit Pointers.

How did JAVA change the world?

Java is a revolutionary programming language that has completely changed the way programming is done by software programmers worldwide. It is estimated that over 6.5 million developers are now using the language across a wide range of devices.

What is Java life cycle?

Life Cycle of Thread in Java is basically state transitions of a thread that starts from its birth and ends on its death.

Why Java does not allow multiple inheritance?

Java doesn’t allow multiple inheritance to avoid the ambiguity caused by it. One of the example of such problem is the diamond problem that occurs in multiple inheritance. To understand the basics of inheritance, refer this main guide: Inheritance in Java What is diamond problem?

Why can’t we implement multiple interfaces in Java?

Ambiguity. That’s the main reason why Java doesn’t support multiple inheritance. Yes, we can implement more than one interfaces in our program because that doesn’t cause any ambiguity (see the explanation below). As you can see that the class implemented two interfaces.

Is Java a pure OOP language?

Even using Wrapper classes does not make Java a pure OOP language, as internally it will use the operations like Unboxing and Autoboxing. So if you create instead of int Integer and do any mathematical operation on it, under the hoods Java is going to use primitive type int only.
