Java Virtual Machine (JVM) executes Java code, but it has been written in platform-specific languages such as C/ C++/ASM, etc.Java code that runs on one platform does not need to be recompiled to run on another platform it's called write once, run anywhere(WORA).Java programs are platform independent which means they can be run on any operating system with any processor as long as the Java interpreter is available on that system.It has obtained its format from C, and OOP features from C++. Java is a set of features of C and C++.James Gosling initially developed Java in Sun Microsystems (which was later merged with Oracle Corporation).
