public final class StringUtils
extends java.lang.Object
The StringUtils class provides static methods that helps make string manipulation easy. The primary functionality it is meant to provide is the ability to split a string into a string array based on a given delimiter. This functionality is meant to take the place of the split(String) and split(String, int) method that was introduced in J2SE-1.4. Please note, however, that the splitting performed by this class simply splits the string based on the delimiter and does not perform any regular expression matching like the split methods provided in J2SE-1.4.
