y 0
count 0

illusObject1 x 3 illusObject2 x 5

FIGURE 8-15 illusObject1 and illusObject2

Now consider the following statement:

Illustrate.incrementY();
Illustrate.count++;

After these statements execute, the objects and static members are as shown in Figure 8-16.

y 1
count 1

illusObject1 x 3 illusObject2 x 5

FIGURE 8-16 illusObject1 and illusObject2 after the statements Illustrate.
incrementY(); and Illustrate.count++; execute

The output of the statement:

System.out.println(illusObject1);
is:

x = 3, y = 1, count = 1

Similarly, the output of the statement:

System.out.println(illusObject2);
is:

x = 5, y = 1, count = 1
Now consider the statement:

Illustrate.count++;
