Write a program whose inputs are three integers, and whose outputs are the largest of the three values and the smallest of the three values.
Problem:
9.20 LAB: Max and min numbers
Write a program whose inputs are three integers, and whose outputs are the largest of the three values and the smallest of the three values.
Ex: If the input is:
7 15 3the output is:
largest: 15 smallest: 3Your program must define and call the following two methods. The method largestNumber() should return the largest number of the three input values. The method smallestNumber() should return the smallest number of the three input values.
public static int largestNumber(int num1, int num2, int num3)
public static int smallestNumber(int num1, int num2, int num3)
Java code:
import java.util.Scanner;
public class LabProgram {
/* Define your method here */public static int largestNumber(int num1, int num2, int num3) {
int largest;
if ((num1 > num2) && (num1> num3)) {
largest=num1;
} else if (num2 > num3 && num2 > num1)
largest=num2;
} else {
largest=num3;
}
return largest;
}
public static int smallestNumber(int num1, int num2, int num3
int smallest;
if ((num1 < num2) && (num1< num3)) {
smallest=num1;
} else if (num2 < num3 && num2 < num1)
smallest=num1;
} else {
smallest=num1;
}
return smallest;
}
public static void main(String[] args) {
/* Type your code here. */Scanner scnr = new Scanner(System.in);
user1=scnr.nextInt();
user2=scnr.nextInt();
user3=scnr.nextInt();
System.out.print("largest: " +largestNumber);
System.out.print("smallest: " +smallestNumber);
}
}
