javac and java (compiler and executable)

[Ratheesh Narayanan]

Hi,

Can any one tell me, in which language java compiler and the interpreter is developed? If java compiler (javac) is written in java language itself how it can be an exe(executable) file? Is this interpreter means JVM?

Thanks in advance,
ratheesh

There is no single answer to your question, because different companies are making different implementations of the Java VM and compiler.

Sun's Java compiler seems to have been written at least partly in Java, because there was a class com.sun.tools.javac.Main in some versions of the JDK (not sure if it still exists in Java 5.0).
