Question

Construct a java program to create a class Person that contains ID number and name. ID and name are initialized by a constructor. Create a new class Employee derived from Person. Employee class takes one additional entry salary and initializes all three variables through a constructor by reusing the definition of parent class constructor. Use an Exception handling mechanism to validate the values of the variables like ID will accept only integers, name accepts only string and salary accepts only double values. If users try to give some other inputs to these variables your program must show an exception. Define a new class Test which creates the objects of the classes for invoking the respective constructors.
