redirecting the output of java compilation to a text file

[polisetty]

i tried to copy the result of the java compilation to the text file using
javac zz.java > compile.txt

It works if the program has no errors and it did not work if it have errors

>and it did not work if it have errors.
Try to execute javac.exe as a subprocess using Runtime.exec method and get error output of subprocess using Process.getErrorStream() method.

String []cmd={"javac.exe","Sample.java"};
     Process proc=Runtime.getRuntime().exec(cmd);
     java.io.InputStream in=proc.getErrorStream();

you can also try,

javac zz.java 2> compile.txt
