Java Tutorial : Java wrapper class(compareTo method) 
WrapperClassTest.java
public class WrapperClassTest
{

    public static void main(String[] args)

        Integer integerObj1 = new Integer(10);
        Integer integerObj2 = new Integer(10);

        /*
         * public int compareTo(Integer anotherInteger)
         * 
         * Parameters: 
         * ----------
         * 
         * anotherInteger - the Integer to be compared.
         * 
         * Returns: 
         * -------
         * 
         * the value 0 if this Integer is equal to the
         * argument Integer; a value less than 0 if this
         * Integer is numerically less than the argument
         * Integer; and a value greater than 0 if this
         * Integer is numerically greater than the argument
         * Integer (signed comparison).
         */
        int result = integerObj1.compareTo(integerObj2);
        System.out.println("result = " + result);

        if (result == 0)
        {
            System.out.println(integerObj1 + " is equal to "
                    + integerObj2);
        }
        else if (result == -1)
        {
            System.out.println(integerObj1 + " is less than "
                    + integerObj2);
        }

        else if (result == 1)
        {
            System.out.println(integerObj1 + " is greater than "
                    + integerObj2);
        }

    }
}
Output
result = 0
10 is equal to 10
