Super String Program - ICSE 2025 Computer Science

Question 5
Define a class to accept a String and print if it is a Super String or not. A String is Super if the number of uppercase letters are equal to the number of lowercase letters. [Use Character and String methods only]


Example: “COmmITmeNt”
Number of uppercase letters = 5
Number of lowercase letters = 5
String is a Super String

Java 
import java.util.Scanner;
class SuperString{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.print("Enter the string: ");
        String s = in.nextLine();
        int upper = 0;
        int lower = 0;
        for(int i = 0; i < s.length(); i++){
            char ch = s.charAt(i);
            if(Character.isUpperCase(ch))
                upper++;
            else if(Character.isLowerCase(ch))
                lower++;
        }
        if(upper == lower)
            System.out.println("String is a Super String");
        else
            System.out.println("String is not a Super String");
    }
}

Output

 
OUTPUT 1:
Enter the string: COmmITmeNt
String is a Super String

OUTPUT 2:
Enter the string: UltraINFO
String is not a Super String
