Lab 3: ( week of 22nd January 2020 )

• String Manipulation Download

Q. NO.	Program	Lab Exercise No.	Remarks
1	WAP to convert a decimal number to a binary number	Lab Exercise No. 5	Solution
2	WAP to convert a decimal number to a octal number	Practice Set No. L3
3	WAP to find the sum of any number of integers interactively, i.e., entering every number from the keyboard, where as the total number of integers is given as a command line argument.	Lab Exercise No. 7
4*	WAP that show working of different functions of String and StringBuffer class like setCharAt(), setLength(), append(), insert(), concat(), and equals()	Lab Exercise No. 8	Concepts of String Handling is required

Lab 4: ( week of 29th January 2020 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Create a Box class consisting of three instance variables: width, height, and depth. Create another class named BoxDemo that: Declares 3 objects of type Box , Assigns values to the instance variables of Box objects, and Finally computes the volume of all 3 Box objects. There are no methods in this class.	Practice Set No. L4
2	Implement Q. NO. 1 using methods. Apply the concepts like methods taking parameter, methods returning values, etc.	Practice Set No. L4(2)
3	Write a program to create a “distance” class with methods where distance is computed in terms of feet and inches, how to create objects of a class and to see the use of this pointer.	Lab Exercise No. 9

Lab 5: ( week of 05th February 2020 )

Q. NO.	Program	Lab Exercise No.	Remarks
1	Create a Box class consisting of three instance variables: width, height, and depth. Create another class named BoxDemo that: Declares 3 objects of type Box , Assign the values of object 1 using Default Constructor(explicit). Assign the values of object 2 using Parameterized Constructor. Assign the values of object 3 using Parameterized Method. Finally computer the volume of all three objects.	Practice Set No. L5
2	Modify the "distance" class by creating constructor for assigning values (feet and inches) to the distance object. Create another object and assign second object as reference variable to another object reference variable. Further create a third object which is a clone of the first object.	Lab Exercise No. 10
3	Write a program to show that during method overloading, if no matching argument is found, then java will apply automatic type conversions(from lower to higher data type).	Lab Exercise No. 11
