Java output console error message to file?

Question

I have a simple piece of code that outputs console text to a text file in Java:

PrintStream out = new PrintStream(new FileOutputStream("test2_output.txt"));
System.setOut(out);

However I require this text file to contain the error messages that is produced in the console but they are not included.

How do I do this?

Solution 1

Add:

System.setErr(out);

at the end.

Solution 2

There is also a System.setErr() call to redirect stderr.

Solution 3

System.setErr(out)

Solution 4

You're currently redirecting the standard output stream to a file. To redirect the standard error stream use

System.setErr(out);

• System.setErr()^javadoc
