Trim Characters from String....Help!

[Jennifer Johnson]

I need to trim leading zero's from a string variable, for example: 0000006566. The number of zero's will not always be the same. Can someone help?
Thank you in advance!

Try this for starters:

public class TestIt {
    public static void main(String[] args) {
        try {
            String v1 = "000456";
            String v2 = "00000123";
            String v3 = String.valueOf(Integer.parseInt(v1));
            String v4 = String.valueOf(Integer.parseInt(v2));
    
            System.out.println("v3 = " + v3);
            System.out.println("v4 = " + v4);
        } catch (NumberFormatException e) {
            System.out.println("These were more than just zero padded Strings");
        }
    }
}

If the string is always going to be an int (it has no characters in it) then Integer.parseInt() will do it for you.

String test = "00012536";
int i = Integer.parseInt(test);
System.out.println(i);

Or a more generic one could be

String test = "00012536";
String temp = "";
   int i = 0;
   while(test.charAt(i)=='0'){
      temp = test.substring(i+1);
      i++;
   }
   System.out.println(temp);

there is probably even a simpler way, but those were the first two that came to mind, hope it helps.

Here's a fancy approach if you want to look cool and show off your knowledge of JDK1.4

String stest="000000506505";
while (stest.startsWith("0",0))
{
stest=stest.replaceFirst("0","");
stest=stest.trim();
}
System.out.println("test="+stest);
