hi there ,
in course of writing a program i needed to input "java source code"
and compile it
in program itself and pipe the compiled "class file" to other tool
called "javap".
so, anybody out there tell me how to invoke "javac & javap " from
source itself

Is that a question? If so, it pays to add a question mark (?).
Another thing that encourages people to read messages,
by making it easier for them to do that, is to use the Shift
Key once at the start of each sentence.
