Question

It needs to be done in JAVA

Please don't use the flag=true method. I need it done in another way.

The user should input the number of numbers they are going to enter. Your job is to find the maximum and the minimum of these numbers. The output of the program if the user does not enter a negative number and all iterations successfully terminate, will be the maximum number, the minimum number and their difference(max-min). If the user inputs a negative number while entering the numbers, you will exit the loop and will not report the min,max and the difference but will write:” Program aborted due to the entrance of a negative number" Exp: The user enters 3 as the number of elements then enters 1,2,4. The output will be: min= 1, max= 4 and the diff is 3. Exp2: The user enters 3 as the number of elements then enters 4,-5. The output will be: "Program aborted due to the entrance of a negative number"

Java code:

import java.util.Scanner;
public class Main{
   public static void main(String[] args){
   Scanner input=new Scanner(System.in);
   //asking for number of elements
   System.out.print("Enter the number of elements: ");
   //accepting number of elements
   int n=input.nextInt();
   //asking for elements
   System.out.print("Enter the elements: ");
   //initializing min,max and number
   int min,max,num;
   //accepting first number
   num=input.nextInt();
   //setting it as min
   min=num;
   //setting it as max
   max=num;
   //loop to accept all numbers
   for(int i=1;i<n;i++){
   //checking if the number is less than 0
   if(num<0){
   //printing Program aborted
   System.out.println("Program aborted due to the entrance of a negative number");
   //exiting Program
   return;
   }
   //checking if the number is minimum
   if(num<min)
   //setting number as minimum
   min=num;
   //checking if the number is maximum
   if(num>max)
   //setting number as maximum
   max=num;
   //accepting next number
   num=input.nextInt();
   }
   //checking if the number is less than 0
   if(num<0){
   //printing Program aborted
   System.out.println("Program aborted due to the entrance of a negative number");
   //exiting Program
   return;
   }
   //checking if the number is minimum
   if(num<min)
   //setting number as minimum
   min=num;
   //checking if the number is maximum
   if(num>max)
   //setting number as maximum
   max=num;
   //printing minimum, maximum and difference
   System.out.println("min= "+min+" max= "+max+" and the diff is "+(max-min)+".");
   }
}

Screenshot:

1 import java.util.Scanner; 2. public class Main{ 3 public static void main(String[] args) { Scanner input=new Scanner(System.in); //asking for number of elements System.out.print("Enter the number of elements: "); 7 //accepting number of elements 8 int n=input.nextInt(); 9 //asking for elements 10 System.out.print("Enter the elements: "); 11 //initializing min, max and number 12 int min, max, num; 13 //accepting first number 14 num=input.nextInt(); 15 //setting it as min 16 min=num; 17 //setting it as max 18 max=num; 19 //loop to accept all numbers 20 for(int i=1;i<n;i++){ 21 //checking if the number is less than a 22 if(num<0){ 23 //printing Program aborted 24 System.out.println("Program aborted due to the entrance of a negative number"); 25 //exiting Program 26 return; 27 } 28 //checking if the number is minimum 29 if(num<min) 30 //setting number as minimum 31 min=num; 32 //checking if the number is maximum 33 if(num>max) 34 //setting number as maximum 35 max=num; 36 //accepting next number

Input and Output:

37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 } num=input.nextInt(); } //checking if the number is less than o if(num<0){ //printing Program aborted System.out.println("Program aborted due to the entrance of a negative number"); //exiting Program return; } //checking if the number is minimum if(num <min) //setting number as minimum min=num; //checking if the number is maximum if(num>max) //setting number as maximum max=num; //printing minimum, maximum and difference System.out.println("min= "+min+" max= "+max+" and the diff is "+(max-min)+"."); }

Enter the number of elements: 3 Enter the elements: 1 2 4 min= 1 max= 4 and the diff is 3. =

Enter the number of elements: 3 Enter the elements: 4 -5 Program aborted due to the entrance of a negative number
