Question

how can i make sure that the converted binary from int is displayed in 4,8,12… decimal place?

like

0000
0001
0010
0011
0100
0101
0110

Pls advice..

public int binary(int n)
{

if (add > count)
{
    System.out.println("break");
    return 0;
}
else
{

    sb=Integer.toBinaryString(add);
    num = Integer.parseInt(sb);
    add++;
}
while (sb.length()%2==0)

{   temp = sb;
    sb = "";
    sb = "0" + temp;
}
    System.out.println(sb);
    return binary(add);
}

Answer 1

is this what you want?

String s = Integer.toBinaryString(yourInt);
        for (int i = 1; i <= s.length() % 4; i++) {
            s = "0" + s;
        }
