Answer 1

Solution:

In the above java program the function isMember() is used with return type boolean , but the actual return part is not boolean in line 32 (Actually it should be some "return true "or"return false " ).In line 44 nothing is returned. "f=true" is an assignment. To avoid compilation errors and to execute the program without errors , this modification of proper return is to done.l "return true "or"return false " is the modification if the return type of the function is boolean.

Everything in the main function is correct. only isMember() is to be modified as explained above.
