Q1
A method is ...
1) an implementation of an abstraction.
2) an attribute defining the property of a particular abstraction.
3) a category of objects.
4) an operation defining the behavior for a particular abstraction.
5) a blueprint for making operations.
Q2
An object is ...
1) what classes are instantiated from.
2) an instance of a class.
3) a blueprint for creating concrete realization of abstractions.
4) a reference to an attribute.
5) a variable.
Q3
Which line contains a constructor in this class definition?
public class Counter { // (1)
int current, step;
public Counter(int startValue, int stepValue) { // (2)
set(startValue);
setStepValue(stepValue);
}
public int get() { return current; } // (3)
public void set(int value) { current = value; } // (4)
public void setStepValue(int stepValue) { step = stepValue; } // (5)
}
