Question

Having a problem converting loop output into an array. I am converting a decimal into binary form but I want it to print out from left to right rather than in a vertical line. I assume there is a way to add the loop output into an array 1 by 1.
My code snipet from the program:

    if (choice == 2)//convert decimal to binary
    {
        System.out.println("Enter a decimal digit between -512 and 511 to convert to binary.");
        decimal = keyboard.nextInt();
        decimal2 = decimal;
        while(decimal > 0){

            decimal2 = decimal % 2;
            decimal = decimal /2;
            System.out.println(decimal2);


        }

    }

Thanks for any help!

Answer 1

You can use a string to concatenate the remainder values.

String ans="";

inside the loop

decimal2 = decimal % 2;
decimal = decimal /2;
ans = decimal1+ans;

outside the loop you print:

System.out.println(ans);
