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
