Answer / y.v.v.d.ravikanth
equals() method is from Object Class.So this is the method
to check the equality between two objects.This method
implements the equalence relation.
ex obj1 o1 = "ravi";
obj2 o2 = "ravi";
o1.equals(o2) ;// returns true.
== Operator. no doubt this is the operator. It can be used
in two ways
1:To compare the values of primitive variables.
2.To compare the object refference variables.
it returns true if refference variable reffering to the
same object.
ex obj1 a
obj2 b
obj1 c
a==c----> returns true.
a==b----> returns false.

Answer / ravikiran
equals will compare two objects,== will compare whether two
reference variables refer to same object or not
| Is This Answer Correct ? | 9 Yes | 1 No |
The Object class equals method refers address comparision.
Person p=new Person();
Person p1=new Person();
if(p.equals(p1){
//is always false.
}
the string class equals method refers content comparision
String p=new String ("java");
String p1=new String ("java");
if(p.equals(p1){
//is always true.
}
Dn't get confusion

Answer / devarathnam c,kotagudibanda(po
Hi...
"equals()" method always compares the content of an
object,but "==" operator compares the memory locations
(references).
eg: String s1="KOTAGUDIBANDA";
Where "s1" is a reference and "KOTAGUDIBANDA"is a content.
