Answer:

A variable of a primitive type contains the actual data, not information on where the data is.

Two Kinds of Variables

	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 to get the data to be printed.

QUESTION 7:

Does using str in the above statement change the information it contains?
