java - How to remove leading zeros from numeric text? -

i using remove leading zeros input string.

return a.replaceall("^0+","");

but above string removes string alphanumeric well. not want that. requirement is:

only leading zeros of numeric numbers should removed e.g.

00002827393 -> 2827393

if have alpha numeric number leading zeros must not removed e.g.

000zz12340 -> 000zz12340

you can check if string composed of digits first :

pattern p = pattern.compile("^\\d+$"); matcher m = p.matcher(a);  if(m.matches()){   return a.replaceall("^0+", ""); } else {   return a; }
