Demo Example 1: Split a String into an Array with the Given Delimiter Exception in thread 'main' Īt (String.java:2324)Īt (StringExample.java:11)Ģ. It will throw NullPointerException in case the method argument is null. The method does not accept ‘null’ argument.

String strArray = 'hello world'.split('[') In given example, '[' is invalid regular expression. Watch out that split() throws PatternSynta圎xception if the regular expression’s syntax is invalid. Public String split(String regex, int limit) 1.2. If the limit is negative then result array can be of any size.The trailing empty strings will be discarded. If the limit is zero then result array can be of any size.The result array’s length will be no greater than limit, and the array’s last entry will contain all input beyond the last matched delimiter. If the limit is positive then the pattern will be applied at most limit – 1 times.limit – controls the number of times the pattern is applied and therefore affects the length of the resulting array.regex – the delimiting regular expression.

The regular expression must be a valid pattern and remember to escape special characters if necessary. The String split() method returns an array of split strings after the method splits the given string around matches of a given regular expression containing the delimiters.
