Questions: Write a program whose inputs are three integers, and whose output is the smallest of the three values. Ex: If the input is: 715 3 the output is: 3

Solution Steps

To read input from the user, we need to import the Scanner class from the java.util package.

import java.util.Scanner;

Define the main class LabProgram and the main method where the program execution will begin.

public class LabProgram {
    public static void main(String[] args) {

Create a Scanner object to read the three integer inputs from the user.

        Scanner scnr = new Scanner(System.in);
        int num1 = scnr.nextInt();
        int num2 = scnr.nextInt();
        int num3 = scnr.nextInt();

Use conditional statements to find the smallest of the three numbers.

        int smallest = num1;
        if (num2 < smallest) {
            smallest = num2;
        }
        if (num3 < smallest) {
            smallest = num3;
        }

Print the smallest number to the console.

        System.out.println(smallest);
    }
}

Final Answer

import java.util.Scanner;

public class LabProgram {
    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        int num1 = scnr.nextInt();
        int num2 = scnr.nextInt();
        int num3 = scnr.nextInt();

        int smallest = num1;
        if (num2 < smallest) {
            smallest = num2;
        }
        if (num3 < smallest) {
            smallest = num3;
        }

        System.out.println(smallest);
    }
}
