Remove Preceding 0 for any String.

Wile developing an application in SAP NWDS.  I got this requirement once, like:

Problem :

There is a String having UserId concatenated with User name followed by '-'. (00001234 - Test Sap, 00000102 - Test1 sap, 00000002 - Test2 sap) . 

The requirement was to get just no. 1234, 102, 2 respectively.

Solution:

1. Split the string followed by space into parts using:
   String pernr = "00001234 - Test Sap";
   String[] tokens = "this is a test".split("\\s");
   
2. Take the substring  tokens[0] and parse it to Integer.
   int result = Integer.parseInt(tokens[0]);
   
3. You will get the required value in result.
   result will have value = 1234 .
