Example: Greatest of Three using Nested Ternary Operator in Java

// Greatest of Three using Nested Ternary Operator
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Initialize Scanner for user input
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt user to enter three numbers
        System.out.print("Enter first number: ");
        int num1 = scanner.nextInt();

        System.out.print("Enter second number: ");
        int num2 = scanner.nextInt();

        System.out.print("Enter third number: ");
        int num3 = scanner.nextInt();

        // Step 3: Use nested ternary operator to find the greatest number
        // (num1 > num2) ? ((num1 > num3) ? num1 : num3) : ((num2 > num3) ? num2 : num3);
        // Explanation:
        // If num1 > num2 is true:
        //    Then compare num1 with num3. The greater of these two is the result.
        // If num1 > num2 is false (meaning num2 >= num1):
        //    Then compare num2 with num3. The greater of these two is the result.
        int greatest = (num1 > num2) ? ((num1 > num3) ? num1 : num3) : ((num2 > num3) ? num2 : num3);

        // Step 4: Display the greatest number
        System.out.println("The greatest number is: " + greatest);

        // Step 5: Close the scanner
        scanner.close();
    }
