Question

Define a class to overload the method format as follows:

void format ():	To print the following pattern using Nested for loops only: 1 2 3 4 5 2 3 4 5 3 4 5 4 5 5
int format (String s):	To calculate and return the sum of the ASCII codes of each character of the String. Example: CAВ Output: 67 + 65 + 66 198
void format (int n):	To calculate and display the sum of natural numbers up to n given by the formula. `(n(n +1))/1`

Answer 1

class MethodOverloader {
    
    // (i) Overloaded method with no parameters to print the nested loop pattern
    void format() {
        for (int i = 1; i <= 5; i++) {
            for (int j = i; j <= 5; j++) {
                System.out.print(j + " ");
            }
            System.out.println();
        }
    }

    // (ii) Overloaded method to calculate and return the sum of ASCII codes
    int format(String s) {
        int sum = 0;
        for (int i = 0; i < s.length(); i++) {
            char ch = s.charAt(i);
            sum += (int) ch;
        }
        return sum;
    }

    // (iii) Overloaded method to calculate and display the sum of natural numbers
    void format(int n) {
        int sum = (n * (n + 1)) / 2;
        System.out.println("Sum of " + n + " natural numbers = " + sum);
    }
