Java Program: Largest of Three Numbers Using Ternary Operator

21. Using the ternary operator, create a program to find the largest of three numbers.

Java 
import java.util.Scanner;


 


public class LargestOfThree {


    public static void main(String[] args) {


        Scanner sc = new Scanner(System.in);


 


        // Input three numbers


        System.out.print("Enter first number: ");


        int a = sc.nextInt();


 


        System.out.print("Enter second number: ");


        int b = sc.nextInt();


 


        System.out.print("Enter third number: ");


        int c = sc.nextInt();


 


        // Finding largest using ternary operator


        int largest = (a > b) ? ((a > c) ? a : c) : ((b > c) ? b : c);


 


        // Output


        System.out.println("Largest number is: " + largest);


 


        sc.close();


    }


}

Output

Sample Input 
Enter first number: 25
Enter second number: 40
Enter third number: 15

Sample Output 
Largest number is: 40

Explanation

  • The ternary operator checks conditions in a compact form:

                 (condition) ? value_if_true : value_if_false

  • First comparison checks between a and b.
  • The larger of those is then compared with c.
  • The final result is stored in largest.
