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 [1]

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.	Lab Exercise No. 2	Read about Packages from javatpoint [2]

Lab 3: ( week of 17^th May 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Define an abstract class Shape in package P1. Inherit two more classes: Rectangle in package P2 and Circle in package P3. Write a program to ask the user for the type of shape and then using the concept of dynamic method dispatch, display the area of the appropriate subclass. Also write appropriate methods to read the data. The main() function should not be in any package.	Lab Exercise No. 3	Read about Inheritance from javatpoint [3] Read about Abstract class from javatpoint [4]

Lab 4: ( week of 24^th May 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Create an Exception subclass UnderAge, which prints “Under Age” along with the age value when an object of UnderAge class is printed in the catch statement. Write a class exceptionDemo in which the method test() throws UnderAge exception if the variable age passed to it as argument is less than 18. Write main() method also to show working of the program.	Lab Exercise No. 4	Read about Exception Handling from javatpoint [5]

Lab 5: ( week of 31^st May 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Write a program to implement stack. Use exception handling to manage underflow and overflow conditions.	Lab Exercise No. 5	Read about Exception Handling from javatpoint [6]

Lab 6: ( week of 07^th June 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Write a program to read characters from console using BufferedReader	Practice Set No. 1	Read about Java I/O from javatpoint [7]
2	Write a program to read string from console using BufferedReader	Practice Set No. 2
3	Write a program that copies content of one file to another. Pass the names of the files through command-line arguments.	Lab Exercise No. 6	Read about File operations in Java from javatpoint [8]

Q. NO.	Program	Lab Exercise No.	Remarks

Lab 10: ( week of 05^th & 12^th July 2021 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Using AWT, write a program to display a string in frame window with pink colour as background.	Lab Exercise No. 10	Read about Adapter Classes from javatpoint [12]
2	Using AWT, write a program to create two buttons named “Red” and “Blue”. When a button is pressed the background color should be set to the color named by the button’s label.	Lab Exercise No. 11
3	Using AWT, write a program which responds to KEY_TYPED event and updates the status window with message (“Typed character is: X”). Use adapter class for other two events.	Lab Exercise No. 12
4	Using AWT, write a program to create two buttons labelled ‘A’ and ‘B’. When button ‘A’ is pressed, it displays your personal information (Name, Course, Roll No, College) and when button ‘B’ is pressed, it displays your CGPA in previous semester.	Lab Exercise No. 13
