Formatting a text field

-----------------------------------

I was wondering how to format a text field to display a 0 infront of numbers less than 10. I am making a digital clock, and need to display the 0 in front, for example "5:02".

DecimalFormat dc = new DecimalFormat("00");
System.out.println("5" + ":" + dc.format(2));


Don't forget to import java.text.DecimalFormat!

System.out.printf("5:%02d", 2);

As a quick note, I believe wtd's use of printf will only work on Java 5.0 or later; if you're using what your school gave you (most likely RTP with the Jikes compiler that implements Java 1.4.2), it won't work. Just to pre-empt any confusion.
