Java string split with "." (dot)

To split a string in Java using a dot (.) as the delimiter, you can use the split method of the String class.

Here is an example of how to do this:

String input = "this.is.a.test";
String[] parts = input.split("\\.");

This will split the input string into an array of strings, using the dot as the delimiter. The resulting array will be: {"this", "is", "a", "test"}.

Note that you need to use a double backslash (\\) to escape the dot, as the dot has special meaning in a regular expression.

I hope this helps! Let me know if you have any questions.
