Code : How to split String

While programming it may requires to split the string into words, to accomplish this one can use ‘StringUtilities’ class like :

StringUtilities su = null;
String[] abc = su.stringToWords("Xyz XYZ xyz xyZ");

Output : abc[0] = “Xyz”, abc[1] = “XYZ”, abc[2] = “xyz”, abc[3] = “xyZ”.

Or you can use following helper method to do the same :

public static final String[] splitString(final String data,      final char splitChar, final boolean allowEmpty) {     Vector v = new Vector();     int indexStart = 0;     int indexEnd = data.indexOf(splitChar);     if (indexEnd != -1) {         while (indexEnd != -1) {             String s = data.substring(indexStart, indexEnd);             if (allowEmpty || s.length() > 0) {                     v.addElement(s);             }             indexStart = indexEnd + 1;             indexEnd = data.indexOf(splitChar, indexStart);          }          if (indexStart != data.length()) {             // Add the rest of the string             String s = data.substring(indexStart);             if (allowEmpty || s.length() > 0) {                  v.addElement(s);             }           }     } else {          if (allowEmpty || data.length() > 0) {              v.addElement(data);          }     }     String[] result = new String[v.size()];     v.copyInto(result);     return result; }

It has the ability to skip any blank lines ( typically split on \n), so it also has the ability to remove any blank sequences it encounters.
