What programming language is used to develop the core Java Development Kit classes?

I know a little bit about programming from doing some basic stuff. I was wondering about an object oriented programming language. What programming language is used to develop another programming language like Java?

  • M. L.:

    The Java virtual machine and compiler are written in C.

    Most of the Java core classes are written in Java. However, a few of the GUI components in AWT and a few base classes (such as String) are written in C with a JNI connector.

  • Alex:

    Java is very similar to basic, in the end Java is based on Java….

  • ?:

    it all boils down to assembly code and machine code in the end since all a computer understands is 1 or 0
