/* 
 SentenceBuilder.java

 Write a Java program called SentenceBuilder that takes words from the user 
 at the command line and constructs a sentence. Concatenate the words and 
 insert spaces to build a sentence. 

 Use a do-while loop and a sentinel to allow the user to tell the program 
 when they have finished entering words. 
 Output the sentence to the command line. Don’t include the sentinel in the sentence!
