Java coding (TMC)

[bomberblyat]

import java.util.Scanner;
public class javacode {
    public static void main(String[] args) {
        Scanner reader = new Scanner(System.in);
        System.out.println("till?");
        int num = Integer.parseInt(reader.nextLine());  
        int i = 0;
        while (num < 3) {
            num += 1;
            i++;
            System.out.println(num);
        }
    }
}

 

this code should give me result like this example:

user gives number 3 to program and program should do this

1

2

3

but mine does 

3

2

1

pls help thx

if you enter the number 3 then num = 3 which means while (3 < 3) results in false. I dont know why it is counting down, I have had too many beers to work it out in my head.

 

If you want to count from one to the number entered then do this:

 

for (int i = 1; i <= num; i++){

        System.out.println(i);

}

Your Code is counting from the Number you enter to 3.

Thats it.

No counting backwards.

Then do what schischka told you.

Way easier with for loop then while.
