Java

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter first number: ");
        double a = sc.nextDouble();
        System.out.print("Enter second number: ");
        double b = sc.nextDouble();
        System.out.print("Enter third number: ");
        double c = sc.nextDouble();

        double largest;

        if (a >= b && a >= c) {
            largest = a;
        } else if (b >= a && b >= c) {
            largest = b;
        } else {
            largest = c;
        }

        System.out.println("Largest = " + largest);

        sc.close();
    }
}

Output

Enter first number: 5
Enter second number: 12
Enter third number: 9
Largest = 12.0

We use a series of comparisons (>=) to determine which of the three numbers is the largest.
