Question

public class Main
{
    /**
     * This is the main routine for this assignment.
     */
    public static void main(String[] args)
    {
        //This is to clear the terminal window. 
        //It will flush the terminal window so it is clear for new output.
        System.out.print("f");
        //Declare the variables
        int n;   //N is for the upper limit to count up to
        int a;   //A is for the divisor for apple numbers

        boolean run= true;

        //create an object of Scanner class
        Scanner input= new Scanner(System.in);
        //Prompt the user to enter a number 
        // that will be an upper limit for my program to count up to
        System.out.println("Please enter a number that will serve as an upper limit");
        n= input.nextInt();
        while (!(n>= 1 && n<=1000000)){
            System.out.println("You need to enter a number between 1 and 1,000,000");
            n=input.nextInt(); //Prompts the user to input correct number
        }
        //Prompt the user to enter a second number

            b=input.nextInt(); //Prompts the user to input correct data
        }

        //Create a counter that starts at 1
        int c= 1;

        //Create a counter for apple and banana numbers
        int ab= 0;

        //while loop continues
        //as long as c is less or equal to n
        // and as long as ab is less than 5

        while(c <= n && ab < 5){
            if( c%a==0 && c%b==0){
                System.out.println( c + " Apple and Banana");
                ab++;
            }else if ( c%a==0&& c%b!=0){
                System.out.println( c + " Apple");
            }else if ( c%b==0 && c%a!= 0){
                System.out.println( c + " Banana");
            }else if (c%b!=0 &&| c%a!= 0) {
                c++;
            }

        }
        input.close();

    }
