Answer 1

saveCustomerInfo() definition doesn't match the invocation. The definition specifies method with parameters, invocation calls it as if the method accepts no parameters.

Answer 2

Look at definition at line 29, you have specified that the method accept parameters.

Next look at line 18, the invocation doesn't pass any argument

Answer 3

Call the method giving it arguments as specified in its definition.

Line 18:
customer.saveCustomerInfo( firstName, secondName, age, roomNumber );
