QUESTION 7:
Does using str in the above statement change the information in it?
A variable of a primitive type contains the actual data, not information on where the data is.
| Characteristics | |
|---|---|
| primitive variable | Contains the actual data. |
| reference variable | Contains information on how to find the object. |
Here is the example program again:
class EgString
{
public static void main ( String[] args )
{
String str;
str = new String( "The Gingham Dog" );
System.out.println( str );
}
}
When the statement
System.out.println( str );
is executed,
the reference in str is used to find the object and
get the data to be printed.
