Java – system Setout redirects back to standard output

System. Setout redirects standard output For example,

FileOutputStream f = new FileOutputStream("file.txt");
    System.setOut(new PrintStream(f));

Each system out. Print will be written to this file My question is, once completed, how do I set the output back to standard?

Solution

Just save and restore it:

final PrintStream oldStdout = System.out;
System.setOut(newStdout);
// ...
System.setOut(oldStdout);
