Lab 1: ( week of 19^th April 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Design a class Complex having a real part (x) and an imaginary part (y). Provide methods to perform the following on complex numbers: a) Add two complex numbers. b) Multiply two complex numbers. c) toString() method to display complex numbers in the form: x + i y.	Lab Exercise No. 1	Read about toString( ) from javatpoint.com [ https://www.javatpoint.com/understanding-toString()-method ]

Lab 2: ( week of 26^th April 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Create a class TwoDim which contains private members as x and y coordinates in package P1. Define the default constructor, a parameterized constructor and override toString() method to display the co-ordinates. Now reuse this class and in package P2 create another class ThreeDim, adding a new dimension as z as its private member. Define the constructors for the subclass and override toString() method in the subclass also. Write appropriate methods to show dynamic method dispatch. The main() function should be in a package P.
