In this program problem, develop three methods with the following steps $.$ The functionality, parameters, and return types are described in the Javadoc comments. Finds the position of the next blank character in a String

design the main method to get a string from the user, invoke countWords method, and display the word count.Your methods should be designed according to the descriptions given above. You should test your program with a minimum of three strings, one of which should have extra spaces between words.
