About Question enthuware.ocpjp.v8.2.1103 :

[schchen2000]

The constructor of the class resolves to the same object each time it is invoked.

Why is this answer choice wrong? Is that because of "each time it is invoked"????

That phrase seems to suggest that the constructor is invoked more than once.

In fact, the constructor of a singleton class is to be invoked ONCE AND ONLY ONCE.

Is that why that answer option is wrong?

Thank you.

That is correct. The constructor is invoked only once.

Thank you.

In the explanation, should it not be

Code: Select all

private static final SpeedSensor theInstance = new SpeedSensor();

instead of

Code: Select all

private static final theInstance = new SpeedSensor();

?
