JVM

JVM is a heart of java, even to some other languages. Jvm is available for any hardware and software platform, this can be classified in to both middleware and platform. It is expressed as “write once run anywhere”, this what makes java more powerful than any other language. The same byte code can be used across any platform, "compile once, run anywhere" in short "write once, compile anywhere". JVM operate on byte code, which is normally generated from Java source code. It also give the power of automated exception handling which provides root cause debugging information for every software error and independent of source code.
