What is the difference between equals() method and == operator

== operator:

•  == operator used to compare objects references.
• used to compare data of primitive data types
• if  we are comparing two objects using "==" operator if reference of both are same then it will returns true otherwise returns false.
• obj1==obj2;
• If we are comparing primitive data type variables then it compares data of those two variables
• Ex: int a=12; int b=12; if(a==b) returns true
