6. 11. 4. Relative indexes are especially useful when creating custom time and date formats

Because of relative indexing, the argument cal need only be passed once, rather than three times.


import java.util.Calendar;

import java.util.Formatter;



public class MainClass {

  public static void main(String args[]) {

    Formatter fmt = new Formatter();

    Calendar cal = Calendar.getInstance();



    fmt.format("Today is day %te of %<tB, %<tY", cal);

    System.out.println(fmt);

  }

}
