4. Consider the following method, between, which is intended to return true if x is between lower and upper, inclusive, and false otherwise.

//precondition: lower <= upper //postcondition: returns true if x is between lower and upper, // inclusive; otherwise, returns false public boolean between(int x, int lower, int upper) { /*missing code */ }

Which of the following can be used to replace /* missing code */ so that between will work as intended?

Question 4 options:

	return (x <= lower) || (x >= upper);
	return (x >= lower) || (x <= upper);
	return (x <= lower) && (x >= upper);
	return (x >= lower) &&(x <= upper);
	return lower <= x <= upper;

5. Consider the following class declaration.

public class IntCell { private int myStoredValue; //constructor not shown public int getValue() { return myStoredValue; }

public String toString() { return "" + myStoredValue; } }

Assume that the following declarations appears in a client class.

IntCell m = new IntCell(); Which of these statements can be used in the client class?

I. System.out.println (m.getValue());

II. System.out.println (m.myStoredValue);

III. System.out.println (m);

Question 5 options:

	III only
	II only
	I and II
	I only
	I and III

6. Consider the following method.

public void conditionalTest(int a, int b) { if (( a > 0) && ( b > 0)) { if (a > b) System.out.println ("A"); else System.out.println ("B"); } else if ((b < 0) || (a < 0)) System.out.println("C"); else System.out.println ("D"); }

What is printed as a result of the call conditionalTest(3, -2)?

Question 6 options:

	C
	B
	Nothing is printed.
	A
	D
