How can Java code run on multiple operating systems?

java is palteform independent Programming language – java program can run on the multiple operating system plateform (OS ) without any modification. Actually , java program is run through a special software machine installed on every OS known as Java virtual machine.

Why Java programs can be run on different operating systems?

Java is considered to be platform independent, because the Java compiler converts the source code to bytecode, which is an intermediate language. Bytecode can be executed on any platform (OS) using JVM (Java Virtual Machine).

Can Java run on all OS?

The meaning of platform-independent is that the java compiled code(byte code) can run on all operating systems. … The compiler converts the high-level language (human language) into a format understood by the machines.

Why can compiled Java programs run on many different platforms?

Java is cross platform because a program’s source code is compiled into an intermediate “bytecode” language. … The bytecode is expected to be executed in the same manner on all hardware platforms with Java Virtual Machines.

Can Java only run on Windows?

Java is cross platform in the sense that a compiled Java program runs on all platforms for which there exists a JVM. (This holds for all major operating systems, including Windows, Mac OS and Linux.)

What is multithreading How does Java support multithreading?

Multithreading in Java is a process of executing two or more threads simultaneously to maximum utilization of CPU. Multithreaded applications execute two or more threads run concurrently. … Each thread runs parallel to each other. Mulitple threads don’t allocate separate memory area, hence they save memory.

What systems can Java run on?

Why is Java considered as dynamic?

Java is considered dynamic because of Bytecode. The source code which is written in one platform that code can be executed in any platform. It loads the class file during runtime only. Hence, any thing that happens in runtime is dynamic.
