converter - java-convert decimal to any binary bit

Question

I'm making a project of converting decimal number into binary. But I have a problem that how can I convert any entered number into binary (I'm using array), here is my code:

    public void Decimal2Binary(int a)
{
    int result []=new int[8];
    for (int i = 7;i >=0; i--,a/=2) {
        result[i]=a%2;
}

I do not need it for just only 8-bit binary result, yet, I need it for any size.

Answer 1

use this function Integer.toBinaryString(int)... and why do you want it to be in a array ? can't it be an array list or big decimal.
