In this article we will see how to split string in Java both by using String’s split() method and StringTokenizer. If you have any doubt on anything related to split string please let me know and I will try to help.
String Split Example JavaLet's see an example of splitting string in Java by using split() function:

In above example we have provided delimiter or separator as “:” to split function which expects a regular expression and used to split the string.Now let see another example of split using StringTokenizer

My personal favorite is String.split () because it’s defined in String class itself and its capability to handle regular expression which gives you immense power to split the string on any delimiter you ever need. Though it’s worth to remember following points about split method in Java
1) Some special characters need to be escaped while using them as delimiters or separators e.g. "." and "|".

If you give limit as 2 it will only creates two strings. For example in following example we could have total 4 splits but if we just want to create 2 we can use limit.

No matter what kind of project you work you often need to split string in Java so better get familiar with these API.
