I want to add prefix to my number. I have number which i want to convert it in 3 digits e.g if i pass 1 than it should return 001. Here is my code.

public int returnThreeDigitNo(int number)
{
    int threeDigitNo = 0;
    int length = String.valueOf(number).length();
    if(length == 1)
    {
        threeDigitNo = 00+number;
    }
    if(length == 2)
    {
        threeDigitNo = 0+number;
    }
    if(length == 3)
    {
        threeDigitNo = number;
    }
    return threeDigitNo;
}

thanks in advance

If you want to display an int with 3 digits you can use:

String.format("%03d", yournumber);

I tried in scala and got a long and unusual error message, in Scala your String format code will now look like this: `val res = "%03d".format(yournumber) ` – Aamir Jan 03 '17 at 04:24
is there a way to do this in javascript? – Johhan Santana Mar 10 '20 at 15:48
