Answer 1

You have several problems:

1. Did not allow user input

2. Did not implement Date.isEarlier() and Date.isLater()

The way I approach the solution:

1. Capture user input "MM/DD/YYYY" using SimpleDateFormat

2. Use default methods Date.equals(), Date.before() and Date.after() to compare dates

import java.text.*;

import java.util.*;

public class TestDate {

// instance variables - replace the example below with your own

private Date date1;

private Date date2;

/**

* Constructor for objects of class TestDate

*/

public TestDate(Date date1, Date date2) {

// initialise instance variables

this.date1 = date1;

this.date2 = date2;

}

public static void main(String[] args) {

SimpleDateFormat sd = new SimpleDateFormat("MM/dd/yyyy");

String dateStr1, dateStr2;

System.out.print("Enter Date #1: ");

dateStr1 = new Scanner(System.in).next();

System.out.print("Enter Date #2: ");

dateStr2 = new Scanner(System.in).next();

System.out.println(dateStr1 + " " + dateStr2);

try {

Date date1 = sd.parse(dateStr1);

Date date2 = sd.parse(dateStr2);

if (date1.equals(date2)) {

System.out.println(date1 + "is equals to" + date2);

} else {

// do nothing

}

boolean early = date1.after(date2);

if (early) {

System.out.println(date1 + " greater than " + date2);

} else {

// do nothing

}

boolean later = date1.before(date2);

{

if (later) {

System.out.println(date1 + " earlier than " + date2);

} else {

// do nothing

}

}

} catch (java.text.ParseException e) {

e.printStackTrace();

}

}

}

it doesn't work cause you never prompt the user for input.  In your  main method you need to prompt the user for the input you want.    You will want to use the Scanner class.
