Answer:
No. The String objects don't change. The reference variable ring is changed in the third 
 statement to refer to a different String than originally. (Its original String becomes garbage, 
which is collected by the garbage collector.)

The Length of a String

The length of a string is the number of characters it contains, including space characters and punctuation.

An empty string has length zero. The length() method of a String returns its length:

public int length(); 

The method takes no parameters, but the () is needed when it is used.

Question 13:
Inspect the following code:
String stringA = "Alphabet " ;
String stringB = "Soup" ;
String stringC = stringA + stringB;

System.out.println( stringC.length() ) ;
What does the code print?
