Method Details

• equal

  public static boolean equal(int one, int two)

• equal

  public static boolean equal(long one, long two)

• equal

  public static boolean equal(boolean one, boolean two)

• equal

  public static boolean equal(Object one, Object two)

  Does not compare class types.

  • classEqual(Object, Object)

• classEqual

  public static boolean classEqual(Object one, Object two)

  This method should be called before beginning any equals methods. In order to return true the method:

  1. The two given objects are the same instance using ==. This also means if both Objects are null then this method will return true (well technically they are equal)
  2. Tests that neither object is null
  3. The the two classes from the objects are equal using ==

  The boilerplate using this method then becomes:

   boolean equals = false;
   if (EqualsHelper.classEqual(this, obj)) {
     TargetClass casted = (TargetClass) obj;
     equals = (EqualsHelper.equal(this.getId(), casted.getId()) && EqualsHelper
         .equal(this.getName(), casted.getName()));
   }
   return equals;
   

  Parameters:

  one - The first object to test

  two - The second object to test

  Returns:

  A boolean indicating if the logic agrees that these two objects are equal at the class level
