Where does Java keep standard library classes? [closed]

Question

Where does Java keep standard library classes like java.util.* on the hard drive under Windows OS?

Answer 1

When you say

import java.util.Date;

you are not reading a file. You are telling the compiler to treat the type reference "Date" as if it was "java.util.Date".

When the compiler later resolves java.util.date it will find it in the JDK's jre/lib/rt.jar file.
