None of the above

Question 3. Question : (TCO 2) Which of the following statements is/are true?

If a method is public, it is considered part of the class implementation.

If you declare an attribute as private, you do not have to worry about tracking down every piece of

code that might have changed the attribute when debugging.

While designing a class you add as many interfaces as possible, trying to cover all possible future

user needs.

All of the above

None of the above

“How many hours do you work?”

Question 6. Question : (TCO 5) Which of the following method pairs are not examples of method

public void roll() ; public int move(int x)

public int charge(int x) ; public int charge(int y)

public int subtract() ; public void subtract()

All of the above

Only B

Question 7. Question : (TCO 5) Consider the following class definition.

public class Rose { private int petals; private double cost; public Rose() { petals = 30; cost = 0.0; }

have a data member called ‘color’?

Yes, as long as the data member is used in the same way.

No, this is not possible because the compiler would not know which data member to use.

Yes, but only if the classes are not in the same namespace.

None of the above

Question 9. Question : (TCO 5) Which error handling technique is the least appropriate when
