Question

Note that the code in the Date object should take care of parsing the line. The Date class needs a toString function that returns a String with the correct information.

To test whether one Date is before or equal to another Date, the Date class should have a compareTo function. The Date class should start with a line like:

The header for the compareTo method should have a header like:

This method should return -1 if this Date is before the other Date, 0 if they are equal, and +1 if this Date is after the other Date.

Explanation / Answer

import java.text.*;

public class Date implements Comparable
{
   String s1;
   Date(String d1)
   {
       s1=d1;
   }
      
  
   public int compareTo(Date other)
   {
       SimpleDateFormat fo = new SimpleDateFormate("dd/mm/yy");
       if (fo(this.s1).equals(fo(other.s1))) return 0;
       return (fo(this.s1).before(fo(other.s1)) ? -1 : 1);      
   }
}

class m
{
   public static void main(String args[])
   {
       Date o = new Date("12/12/12");
       Date o1 = new Date(13/12/12");

       int d = o.compareTo(o1);      
       System.out.println(d);
   }
}
