Picture of the Objects

Points b and c were constructed with the statements

    b = new Point( 12, 45 ); 
    c = new Point( b );

The constructor for point c is supplied with data in the form of point b. It seems reasonable that the x and y of c will take their values from b. (To be sure, check the documentation. )

After the three objects have been created (just before the program closes) the situation looks like this:

Each reference variable has an object it refers to. Each object contains its data and its methods (for clarity, only some methods are shown.) An object does not contain any constructors (they are only for the class to use.)
