What does it mean by "write once run everywhere" ?

Answer 1

I believe it means that Java code can be run on any platform, which is its greatest advantage. With the rest of the programming languages you need to re-write the code to be able to do that, except for the interpreted languages like JS and Python which would also run anywhere, but at least for me they are still not suitable for creating desktop applications.

Answer 2

write a block of code and call it everywhere and at anytime you want to (eg. a method)

Answer 3

Java uses JVM (Java Virtual machine) so that it compiles java source code into bytecode so any platform can run java program. That's why it says write once and run everywhere.

Answer 4

it means the fact that Java can run in every Operative System so if you write a program in java you dont need to worry about the platform
