Whitespaces in java

What are kinds of whitespaces in Java? I need to check in my code if the text contains any whitespaces.

My code is:

if (text.contains(" ") || text.contains("\t") || text.contains("\r") 
       || text.contains("\n"))   
{  
   //code goes here
}   

I already know about \n ,\t ,\r and space.
