I can not help but wonder how Java is different from other languages when I am in my introductory Java class. I found out what makes Java different from other languages. The huge Java Class Library is one of the unique features.
To answer this question thoroughly, Java needs to be compared to each language. In the next section, Java is compared to other major programming languages that are used today. C, C#, C#, C++, Javascript, Ruby, and Python are included in this.
The class library in Java is as much a part of the language as the actual Java itself. The real challenge of learning how to use Java is not learning the programming language at all, but learning the application programming interface.
On top of that, if you are from a C, C++ background, then you will find Java quite similar, especially in terms of its syntax. On the other hand, experts who are working in Oracle, Sun, and SCRUM can easily combine their knowledge with Java to develop mobile web or applications.
Why is Java known as the platform independent programming language?
To tackle the diversity of platforms, such applications should be written independently. Java can be used to write applications that are not dependent on the hardware and operating systems. A platform-independent programming language is what it is.
Java is called Platform Independent because it is possible to run programs on multiple platforms without re-writing them for a particular platform.
Write once run anywhere is practically a platform independent meaning. Java is called so because of the fact that it can run on any system regardless of its underlying operating system. Java is a platform-independent language, which means that we can run the same code on multiple platforms.
Java uses Byte Code and the JVM to achieve this. byte code is the programming code that is converted into java code. Byte code is platform-independent and can be run on any processor.
The java compiled code can run on all operating systems according to the meaning of platform-independent. platform-independent. A program is written in a language that can be understood by humans. It might contain words that the machine does not understand.
For the source code to be understood by the machine, it needs to be understood in a machine-level language. There is a role of a compiler here. The high-level language is converted into a format that the machines understand.
A program that converts the source code for another program from a programming language into code is called a program thattranslates.
There is a platform independent language called JAVA. bytecode is a type of code that is unique to Java and is produced by the Java compiler. When the java program runs in a particular machine, it is sent to the java compiler, which converts the code into the intermediate code called bytecode.
This code is sent to a Java virtual machine which resides in the operating system's memory. It is possible for the JVM to recognize the platform it is on and convert the bytecodes into native machine code. The platform independent language is called java.

Why does high-level programming language like Java needs to be translated into machine language?
High-level languages like C and JAVA are very close to English. It makes the process of programming simpler. It needs to be translated into machine language before it can be executed. The translation process can either be conducted by a compiler or an interpreter. The source code is also known as source code.
The machine languages are very close to the hardware. The machine language on every computer is different. A machine language program is made up of a series of patterns. There is an expression that means "Eg." The operations which should be performed by the computer are represented.
It is possible to run machine language programs directly from an executive program.
The machine-level language consists of a set of instructions that are in the form of 0 or 1. The instructions given to the computer can only be understood by machines with 0 and 1 digits as the digits.
It is difficult for programmers to write a program in machine instructions, as it is not easy for them to create a program in a machine-level language. It is difficult to understand, and its maintenance is very high.
A machine-level language is not portable as each computer has its own machine instructions, so if we write a program in one computer, it won't work in another computer.
The problems which we were facing in machine-level language can be reduced to some extent by using an extended form of machine-level language known as assembly language. Since assembly language instructions are written in English, it is easier to understand.
