Java Function-Overloading Board Questions

  1. Define a class to overload the method perform as follows: [15 MARKS-2024]

    (i) double perform (double r, double h) — to calculate and return the value of curved surface area of cone
    CSA = πrl, l = √(r2+ h2)

    output
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

  2. Define a class to overload the function print as follows: [15 MARKS-2023]

    (i) void print() - to print the following format

    1  1  1  1
2  2  2  2
3  3  3  3
4  4  4  4
5  5  5  5
    (ii) void print(int n) - To check whether the number is a lead number. A lead number is the one whose sum of even digits are equal to sum of odd digits.

    e.g. 3669
odd digits sum = 3 + 9 = 12
even digits sum = 6 + 6 = 12
3669 is a lead number.
