Show all numbers witch divides by 30

Hi. This is my first post, I just started programming in uniersity, so please be soft... :)

I am giving to program number from 1- 10000 it must print out all numbers witch can divide by 30.
Something is terrible wrong with loop statement in end. I hope you can help me.

Code:

---

import java.util.Scanner;

public class CheckNumberRange
{

        public static void main(String[] args)
        {
                Scanner keyboard = new Scanner(System.in);

                System.out.println("Write number between 1 - 10'000: ");
               
               
                int x = keyboard.nextInt();
                int legalNumbers = x / 30;
               
                int allNumbers = 0;
               
       
               
                       
                if

                (x > 0 && x < 10000)
                {

                        System.out.println("Number is correct");
                }

                if (x < 0 || x > 10000)
                {

                        System.out.println("Sorry you entered wrong number");
                }
               
                {
                //check if x is working
                        System.out.println("Entered number was: " + x);
                        System.out.println("Number " + x + " divides " + legalNumbers + " times with divider 30");
                       
                       
                        System.out.println("___________________________________________");
                       
                       
                        //show all numbers witch are divided with x
                       
                        for (int i=30; i<=1000; i = 30 + i)
                                allNumbers = i+x%30;
                               
                       
                        System.out.println("Numbers witch are dividable with 30 are " + allNumbers);
                }
               
                               
               

        }

}

1.) Your first if check is useless.
2.) allNumbers is just an integer. It can only hold one integer at a time. It doesn't make sense to call it allNumbers in the hope that it will somehow be able to print all numbers.
4.) Your for loop should not go to 1000, should it? Shouldn't go as far as x, the input number?
3.) Better print the number at each pass of the loop. Loop from 1 to x and at each pass print out the number only if it is divisible by 30.

instead of the second if() statement you could use the else of the first if...much simple
