regex - How to use split() to remove all delimiters from a sentence in Java? -

string text = "good morning. have class. " + "have visit. have fun!"; string[] words = text.split("[ \n\t\r.,;:!?(){"); 

this split method provided in text book, meant remove delimiters in sentence white space character not working , throws regex exception disappointment....i wondering here make work? requirement after split method, in `string[] words either english words without delimiters attaching or whitespace character! lot!

you missing closing ] in character class:

string[] words = text.split("[ \n\t\r.,;:!?(){]"); 

btw can (and better option):

string[] words = text.split("\\w+"); 

to split on non-word character.
