Thread: Why is my code not working?

Hi guys, im learning java and i have an assigment to to input 100 number and then show the highest number and when it was inputed (exe, 1,5,2 shows the number 5 and 2 (2 means second input) now ive writting the code and the result is

Input a number
15
1
1
1
1
15 Was inputed 1

This is ok,but when i try to put the highest number last it shows as follows:

Input a number
1
2
3
4
5
4 Was inputed 4

I understand that the problem is that when the last number is inputed it dosent enter the loop so value dosent get its new "value",but i dont know how to work around it,something is wrong with while part i gusses but i cant figure it out

The code:

package page25;
 
import java.util.Scanner;
 
public class Drill9 {
 
	public static void main(String[] args) {
		System.out.println("Input a number");
 
		Scanner scan = new Scanner(System.in);
		int num = scan.nextInt();
		int counter = 1, value = 1, max = 0;
 
		while (counter < 5) {
			if (num >= max) {
				max = num;
				value = counter;
					counter++;
 
			}
 
	num = scan.nextInt();
 
		}
 
		System.out.println(max + " Was inputed " + value);
 
	}
 
}

why it dosent work

What does that mean?
Can you copy the full contents of the console window from when you execute the program and paste it here?
Add some comments explaining what is wrong with the current output
and show what the desired output is.

Ok. How are you trying to debug the code to find the problem?
One way is to add some print statements that show the values of variables as the program executes so you can see what the computer sees.
For example print out the values of num and num2 immediately after the while and before the if statement.

changing stuff and hoping it works

Often that is not the best approach. Having a good design for a program then debugging the code to see why it is not following the design can be a better approach.

What are the values of the variables as the code executes?
What happens in the loop when the 5 is read?

Current counter4
5

What happens in the loop after the 5th number is read? What is the value of counter? How does the while loop condition evaluate with that value in counter? Will the loop go another time allowing for the value of the 5th number to be compared and saved if appropriate?

Also change the values that are entered so they are not ascending. For example: 11, 2, 33, 4, 55

Glad you got it working. It often helps people to see the logic if there are comments:

             counter++;                  //  set index for next number
             int num = scan.nextInt(); // read the next number

Another hint when searching for max (or min) set the initial value to be at the end of the range:
For example max at -999999999
and min to 9999999999
Then the first compare will always be true and will be saved as the max/min value
