Getting the lowest and highest value from integers without using arrays?

Question

I\'m trying to write a class which reads 5 integers from the user and returns the highest and lowest value back. This must be done using loops and without using arrays and I

Answer 1

Why not just repeat your max logic for min?

public class Ovning_321 {
    public static void main(String[] args){

        Scanner input = new Scanner(System.in);
        System.out.print("Give me an integer: "); 

        number = input.nextInt();
        int max = number;
        int min = number;

              for (int x = 0; x<4; x++){ 
                    System.out.print("Give me an integer: "); 
                    number = input.nextInt(); 

                    if (number > max){ 
                        max = number;  
                    }

                    if (number < min){ 
                        min = number;  
                    } 
              }                 
              System.out.println("Highest value: " + max);
              System.out.println("Lowest value: " + min);
        }
 }

Note that max and min are initially set to the first number that the user enters, so there will be no false 0's and no need to MAX_INT or MIN_INT. This in turn makes the loop run once less so terminate at i == 4 instead of 5.

here you go :)

import java.util.Scanner;

    public class Ovning_321 {
        public static void main(String[] args){
            Scanner input = new Scanner(System.in);
            int number;
            int max = 0;
            int min = 0;

                  for (int x = 0; x<5; x++){ 
                        System.out.print("Give me an integer: "); 
                        number = input.nextInt(); 

                        if (x == 0 || number > max){ 
                            max = number;  
                        }               
                        if (x == 0 || number < min){ 
                            min = number;  
                        }               
                  }                 
                  System.out.println("Highest value: " + max);
                  System.out.println("Lowest value: " + min);
            }
     }
