Why Java is both compiled and interpreted language which feature makes it platform independent?

Why Java is a platform independent language?

Java is platform-independent because it does not depend on any type of platform. Hence, Java is platform-independent language. In Java, programs are compiled into byte code and that byte code is platform-independent. … Any machine to execute the byte code needs the Java Virtual Machine.

Why Java is platform independent and JVM is platform dependent?

JVM is platform dependent because it takes java byte code and generates byte code for the current operating system. So Java software is platform dependent but Java language is platform independent because different operating system have different JVMs.

Why is Java interpreted and not compiled?

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then interprets / executes at runtime. Java source code is compiled into bytecode when we use the javac compiler.

Why pointers are not used in Java?

So overall Java doesn’t have pointers (in the C/C++ sense) because it doesn’t need them for general purpose OOP programming. Furthermore, adding pointers to Java would undermine security and robustness and make the language more complex.

Due to pointers, most of the users consider C-language very confusing and complex.

Why is C platform dependent?

C Compiler is platform dependent since it is closely linked to the OS kernel which is different for different OS. But over the years all OS’s come with pre-installed compilers and libraries that make it quite platform independent for basic programming.

Is Java is a structured programming language?

As its name suggests, structured programming is done in a structured programming language and PHP, C#, C++, Java, Visual Basic, and Python are such languages. The structured programming concept was formalized in 1966 by Corrado Böhm and Giuseppe Jacopini.
