incompatible types: Object cannot be converted to String

on this line :

Answer 1

A String is an Object, but an Object is not necessarily a String.

You try to use variables which are Objects where the compiler expects Strings, and the compiler tells you so. Perhaps the emt1, emt2, emt3 and emt4 variables should have been declared as String? (Hard to tell from the snippet given).
