a == b, a is b

why the answers of "obj1 == obj2" & " obj1 is obj2" are different? (somtimes)

Object has reference not values so comparison will be based on object reference. The equality operator "==" will works well with primitive values not for reference values. For object comparison u need to overload equals() and hasCode() methods in the class. So in ur case obj1 and obj2 may have different references i.e. their hasCode values will be different.
