System has a setOut() method you can pass a PrintStream reference to. Read the API.The question is: why do you want to change System.out if you simply want to print to a file, when you simply could use a PrintWriter wrapped around a FileWriter?

Here is sample code for that:

static{

try {

PrintStream obj_ps = new PrintStream(new FileOutputStream("internal.log"));

System.setOut(obj_ps);

System.setErr(obj_ps);

}

catch (FileNotFoundException ex) {

JOptionPane.showMessageDialog(null, "Error creating log file", "Error", JOptionPane.ERROR_MESSAGE);

}

}
