equals

public boolean equals(Object)
Description copied from class: Object
Determines if this object is "equal" to another object.

In general, objects should be instances of the same class with the same guts to be considered equal. For example, the code below only prints same value since s and t are different strings though they have the same value: "hello".

 String s = new String("hello");
 String t = new String("hello");
 if (s.equals(t)) System.out.println("same value");
 if (s == t) System.out.println("same string");

 

Overrides:
equals in class Object
Following copied from class: java.lang.Object
Parameters:
is - the other Object to which this one is compared
Returns:
true if this Object is equal to other
