Equivalent of freopen in Java

Question

Please suggest a method to obtain a similar behaviour in Java as when we do freopen("filename","r",stdin) OR freopen("filename","w",stdout) in C.

I am new to Java. I know C++ properly. So if you could please provide a code snippet. I just know how to read from stdout through bufferedReader. — avd, May 08 '10 at 11:39

Assuming that this is to redirect stdin/stdout/stderr, have a look at System.setIn and friends. They allow you to assign a different InputStream and PrintStream to System.in, System.out and System.err.
