How do I write the exception from printStackTrace() into a text file in Java?

Question

I need to capture the exception in a text file in Java. For example:

try {
  File f = new File(\"\");
}
catch(FileNotFoundException f) {
  f.printStackTrac

It accepts a PrintStream as a parameter; see the documentation.

File file = new File("test.log");
PrintStream ps = new PrintStream(file);
try {
    // something
} catch (Exception ex) {
    ex.printStackTrace(ps);
}
ps.close();
