Splitting string using period or dot or any basic symbol in Java

Have you tried splitting a string in Java using the period or dot (.) with the inbuilt method split. On trying str.split(“.”) will give you an array of zero elements. This is because unlike Javascript, java wants a regular expression as the parameter for split method. You can solve this simply by giving regular expression instead of simple ‘.’ like this :

String fieldId = “”;
String[] s = fieldId.split(“\\.”);
System.out.println(“Length of splitted array :: ” + s.length);

The output will show you Length of splitted array :: 5

The same expression applies to comma (,) as well as pipe symbol also  (|).

Just scribbled down the issue I just faced, hope this will come to help for someone like me also.

Happy Coding Guys… 🙂

    Thanks a lot! This was a bit confusing for the last half an hour to say the least! It should throw some kind of error or message to tell the user what’s going on here.
