maybe you haven't include java.util.*

important part of string

important part of string split method is that it accept regular expression rather than simple string which gives you immense power on splitting. you can also see some string split examples here.

I have got the same problem

I have got the same problem with split and I have include java.util.*

It ran perfectly for me and I

It ran perfectly for me and I have also checked that there is split() method exists in String class itself . there are two even one take regex also. you can also check this post to learn more about String vs StringBuffer vs StringBuilder to know more about String.
