Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere , meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers.

There were five primary principles in the creation of the Java language:

1.It must be simple, object-oriented, and familiar.

2.It must be robust and secure.

3.It must be architecture-neutral and portable.

4.It must execute with high performance.

5.It must be interpreted, threaded, and dynamic.

Java is portable

The source code i.e. .java file has been compiled and converted to bytecode. Bytecode can be run on any machine that has a Java virtual machine. Java virtual machine changes the bytecode into code that is computer hardware runnable.

Java code is Robust

A program written in Java is called robust because it contains no reference to external data i.e. it does not has any explicit pointers. While other programming languages such as C++ and some others have pointers.

Java is object-oriented

Creating an object of the class is creating an example of a class. Java is object-oriented i.e. it creates examples of each class that are copies of the class. The advantage of creating objects is several examples of the same code and changes are made to that object without modifying the main code.

Java is easy to learn

Java is easy to learn because it eliminates useless and complex features such as operator overloading, explicit pointers, etc. In addition, Java has a syntax similar to C++ and it’s relatively easy, especially for people with a background in C. It was created to produce a language that’s easy to learn, use, compile and debug, and therefore Java is much simpler than other programming languages.

Java is secure

It provides high security due to its excellent exception handling mechanism. Java’s exception handling mechanism is best. Most errors are caught in Java. Errors like division by zero cannot be handled by any programming languages such as C/C++. The high security of Java makes it better and therefore different from other programming languages.

Reasons why Java is better than other Programming languages?

JAVA vs C

Java is object-oriented while C is procedural.
C uses the top-down method while JAVA uses the base up approach.
Java supports overloading while C does not support overloading by any method.
Not exactly like C, JAVA does not support preprocessors, macros, etc.
Various new components, uncommon cases dealing with, modified memory-organization, nearby strings, etc.

JAVA vs C++

Java was originally derived from C++.
C++ is both procedural as well as object-oriented programming language while Java is a pure object-oriented language.
Both languages have different objectives, which means that there are many differences.
Java does not support the operator for overloading but C++ supports it.
C++ also enhances the C programming language whereas while Java is basically designed to support network computing.
Java does not support structures and unions where C++ supports it.
Java is much slower than C++ in terms of execution.
C++ libraries are simple and they are also robust. It also provides containers and associative arrays. But Java has a powerful cross-platform library.
In Java, there is automatic garbage collection while C++ does not have the same. Java supports automatic garbage collection whereas C++ does not support automatic garbage.

JAVA vs PYTHON

Python is a high-level language. It fully supports object-oriented programming. Python is not a pure object-oriented language.
Python is an interpreted language while Java is not an interpreted language, it is a compiled language.
Many large organizations like Google, Yahoo, NASA, etc. are using Python. But Python programs are usually expected to run slower than Java programs.
Java has better library support for some cases of use cases than Python that is java’s biggest advantage.

JAVA vs RUBY

Ruby and Java have a lot of things that are common, starting with the fact that both are object-oriented languages and are strongly typed.
Java is statically typed while Ruby is dynamically typed.
There is a different method of both languages to execute the code. Java first converts code into a machine language so that it can be understood by it and because of this Java code runs faster than Ruby’s code.
Both Java and Ruby provide inheritance and have both public, private and protected methods.

JAVA vs PHP

PHP is a server-side scripting language while Java is a common purpose language. These two languages are exceptional and usually far-reaching at a very basic level.
A big difference between the two is that in PHP, JVM is restarted after every request; This may result in additional performance problems. A programmer should select PHP if he/she doesn’t have a lot of time to complete the project but should go for Java if the project highlights features like scalability, performance, and security.
