About equals ()

The equals() method returns true when the passed object is considered the same as the object that the caller of the method used, otherwise it returns false. A simple example is as follows:

    Integer i = 25;
    Object o = new Object();
    System.out.println(i.equals(o));

The example above will print false to the console.

The equals() method is expected to match both objects and return whether the objects are similar. There are many rules that this method has to adhere to. Again, these are explained in the Java chapter, as typically Java developers will have to write these methods themselves.
