title: Java: Literal percent sign in printf statement
body: <p>I'm trying to add an actual percent sign into a printf statement in Java and I'm getting the error:</p>
  
  <pre><code>lab1.java:166: illegal escape character
                  System.out.printf("%s\t%s\t%1.2f\%\t%1.2f\%\n",ID,pattern,support,confidence);
                                                   ^

  <p>I can't figure out how to put an actual percent sign into my printf? I thought using \% to escape it would work, but it isn't.</p>
  
  <p>Any ideas?</p>
