We know ,in java ,there are jar files that include classes needed. But whereare the jar files of java itself?For example,I can't find the java.lang.Class. I can't find where is the folderwhich contains the Class.java.Can u help me?
look for tools.jar...............
these jar files are in the java directory when u install the SDK!
I think the source (.java) files is in sc.jar and the .class filesare in rt.jat, but just look tyhrough all the jar files in your sdkdirectory
