Strings and Object References in Java

The String class is used for text manipulation. As you read, you will learn different ways to create Strings, methods to manipulate Strings, the String concatenation operator '+', and about how Strings are immutable.

13. The Length of a String

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.

String	length
`"element"`	`7`
`"x"`	`1`
`""`	`0`
`"Look Homeward"`	`13`
`" Look Out "`	`13`

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?
