"==" is the operator which used for assign the value in variable where the other hand "&" is  used for asign the address of variable to another variable!!!!

"==" operator is used to check whether two OBJECTS are equal. In java for STRING type only they have written implementation for this operator, for other types(int etc) the user have to write implementation. 

"&" is used for performing bitwise operation.

1. == operator can be used to check two operands can be equal or not
2. & means address operator it stores the address of a variable

Ex:
1. a=20;b=20;
if (a==b)
System.out.println("both are eual");

2.a=55;
b=&a;
System.out.println("address is="+b);

Result: address is=123458adf(address of a)
