5.6 (Conversion from miles to kilometers) Write a program that displays the following two tables side by side:

public class ProgrammingEx5_6 {
 
 public static void main(String[] args) {
  final int END = 10;
  final int MILES_START = 20;
 
  // printing table header
  System.out.printf("%-9s%15s", "Miles", "Kilometers");
  System.out.print("\t|\t");
  System.out.printf("%-9s%15s\n", "Kilometers", "Miles");
 
  for (int j = 0, i = 1; i <= END; i++, j += 5) {
   System.out.printf("%-9d%15.3f", i, i * 1.609);
   System.out.print("\t|\t");
   System.out.printf("%-9d%15.3f\n", MILES_START + j,
     (MILES_START + j) / 1.609);
 
  }
 
 }
}
