Write a java program making use of methods that finds the smallest of any three numbers that the user inputs. You must use JoptionPane to input the three numbers. A first method must be called and used to develop logic to find the smallest of the three numbers. A second method must be used to print out that smallest number found.

Answer:

import javax.swing.JOptionPane;

public class num3 {

   public static void main(String[] args) {

       String val1 = JOptionPane.showInputDialog("enter first number","value1");

       int num1 = Integer.parseInt(val1);

       String val2 = JOptionPane.showInputDialog("enter second number","value2");

       int num2 = Integer.parseInt(val1);

       String val3 = JOptionPane.showInputDialog("enter third number","value3");

       int num3 = Integer.parseInt(val1);

       //Calling findMin Method

       int minimum = findMin(num1,num2,num3);

       //Calling printMin to print the minimum

       printMin(minimum);

   }

   public static int findMin(int num1, int num2, int num3){

       int min;

       if (num1<num2&&num1<num3){

         min = num1;

       }

       else if(num2<num1&& num2<num3){

           min = num2;

       }

       else{

           min = num3;

       }

       return min;

   }

   public static void printMin(int n){

       JOptionPane.showMessageDialog(null, "The minimum is "+n);

   }

}

Explanation:

  • Import javax.swing.javax.swing.JOptionPane;
  • Use the input dialog method to receive three values
  • convert these values to integers using the Integer.parseInt method
  • Create the method findMin () which uses if and else statements to find the minimum of the three numbers
  • Create method printMin which uses the showMessageDialog method to print the minimum value
  • Call both methods in the main method
