No. Constructors always create new objects. (They might get data from an old object, but a completely separate object will be constructed using a different chunk of main memory.)
The example program has been modified to create a second Point
object.
In the "After" picture, the first object is shaded to
emphasis that it is now "garbage."
The reference variable pt
now refers to the newly created object.
import java.awt.*; class ChangingData2 { public static void main ( String arg[] ) { Point pt = new Point( 12, 45 ); // construct a Point System.out.println( pt ); pt = new Point( -13, 49 ) ; // construct a new Point System.out.println( pt ); } }
What will this second version of the program output to the monitor?
