Does using str
in the above statement change the information in it?
No. Using the information does not change it. This is the same as with primitive variables: using them (in an arithmetic expression, say) does not change their information.
Here is a slightly larger version of the example program, now with a new variable of a primitive type:
class egString2 { public static void main ( String[] args ) { String str; long value; str = new String( "The Gingham Dog" ); value = 32912; System.out.println( str ); System.out.println( value ); } } |
When the statement
str = new String( "The Gingham Dog" );
is executed, a new object is created and a reference to it is placed in str
.
The variable str
now refers to the String object.
