title: Print a boolean value with printf
body: <p>I want to print a <code>boolean</code> value with the <code>printf</code> ,but I do not know how. What I am looking for is something like this imaginary code</p>
  
  <pre><code>boolean car = true;
  System.out.printf("%b",car);
  </code></pre>
  
  <p>The expected output should be:</p>
  
  <pre><code>true
  </code></pre>
  
  <p>How should I do it? Or are there any other ways to get that expected output?</p>
