Answer 1

Answer:

import java.util.Scanner; /* * Java Program to find largest and smallest of three numbers */ public class Main { public static void main(String args[]) { // creating scanner to accept radius of circle Scanner scanner = new Scanner(System.in); System.out.println("Welcome in Java program to find largest and smallest of three numbers"); System.out.println("Please enter first number :"); int first = scanner.nextInt(); System.out.println("Please enter second number :"); int second = scanner.nextInt(); System.out.println("Please enter third number :"); int third = scanner.nextInt(); int largest = largest(first, second, third); int smallest = smallest(first, second, third); System.out.printf("largest of three numbers %d, %d, and %d is : %d %n", first, second, third, largest); System.out.printf("smallest of three numbers %d, %d, and %d is : %d %n", first, second, third, smallest); scanner.close(); } /** * Java method to calculate largest of three numbers * * @param first * @param second * @param third * @return maximum or largest of three */ public static int largest(int first, int second, int third) { int max = first; if (second > max) { max = second; } if (third > max) { max = third; } return max; } /** * Java method to calculate smallest of three numbers * * @param first * @param second * @param third * @return minimum or smallest of three */ public static int smallest(int first, int second, int third) { int min = first; if (second < min) { min = second; } if (third < min) { min = third; } return min; } } Output Welcome in Java program to find the largest and smallest of three numbers Please enter the first number : 1 Please enter the second number : 2 Please enter the third number : 3 largest of three numbers 1, 2, and 3 is : 3 smallest of three numbers 1, 2, and 3 is: 1
