https://meetup.com/fosscafe CC BY NC-SA 4.0 What makes JVM special ? ● JVM is a program that looks like a machine to the programs written to execute in it. ● JVM is a register based abstract machine that works with java byte code. ● Each JVM implementation for a specific OS, translates the Java programming instructions into instructions and commands that run on the local operating system. ● Java programs are written to the same set of interfaces and libraries. Hence platform independent.
