Equivalent to freopen in Java

Question

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

Answer 1

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

Answer 2

See the web page below. There is a solution to what you want to do.
