Deleting leading substring from a string

[MarkusKlein]

Hey guys,

how can i delete a string from a leading substring?

e.g.: "00022521" should become "22521".

thx

Markus

I actually had written a little static class to handle just this. Here is the static class.

public class LeadingZeroRemover {

	public static String removeLeadingZeros(String str) {
		if (str == null) {
			return null;
		}
		char[] chars = str.toCharArray();
		int index = 0;
		for (; index < str.length(); index++) {
			if (chars[index] != '0') {
				break;
			}
		}
		return (index == 0) ? str : str.substring(index);
	}
}

Then you can simply use it like this.

<b>LeadingZeroRemover.removeLeadingZeros</b> (soldToNumber.getValue().toString())

String STR = new String("00022521");

while ( STR.charAt(0) == '0' )

STR = STR.substring(1);

If you care ONLY about leading ZEROES than:

new Integer("0000222521").toString();

Hi Markus,

String string1 = "00022521";

String string2 =string1.substring(3,string1.length);

Hope it helps,

Kind Regards,
