    <p>You could write a convenience method:</p> <pre><code>public PrintStream print(String format, Object... arguments) { return System.out.format(format, arguments); } </code></pre> <p>But as you can see, you've simply just renamed <code>format</code> (or <code>printf</code>).</p> <p>Here's how you could use it:</p> <pre><code>private void printScores(Player... players) { for (int i = 0; i &lt; players.length; ++i) { Player player = players[i]; String name = player.getName(); int score = player.getScore(); // Print name and score followed by a newline System.out.format("%s: %d%n", name, score); } } // Print a single player, 3 players, and all players printScores(player1); System.out.println(); printScores(player2, player3, player4); System.out.println(); printScores(playersArray); // Output Abe: 11 Bob: 22 Cal: 33 Dan: 44 Abe: 11 Bob: 22 Cal: 33 Dan: 44 </code></pre> <p>Note there's also the similar <code>System.out.printf</code> method that behaves the same way, but if you peek at the implementation, <code>printf</code> just calls <code>format</code>, so you might as well use <code>format</code> directly.</p> <ul> <li><a href="http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html" rel="noreferrer">Varargs</a></li> <li><a href="http://download.oracle.com/javase/7/docs/api/java/io/PrintStream.html#format%28java.lang.String,%20java.lang.Object...%29" rel="noreferrer"><code>PrintStream#format(String format, Object... args)</code></a></li> <li><a href="http://download.oracle.com/javase/7/docs/api/java/io/PrintStream.html#printf%28java.lang.String,%20java.lang.Object...%29" rel="noreferrer"><code>PrintStream#printf(String format, Object... args)</code></a></li> </ul>
