title: How do I escape the ',' character in System.out.format?
body: <p>I want to output two numbers separated by a comma using <code>System.out.format</code>. I tried to escape it with %, but it didn't help.</p>
  
  <p>Target output should be in the form of (0.92,0.91)</p>
  
  <pre><code>System.out.format("(%.2f% %.2f)%n", x, fx);
                           ^--- I want to add a ',' character here
