Consider the following incomplete class: public class SomeClass { public static final int VALUE1 = 30; public static int value2 = 10; private int value3 = 5; private double value4 = 3.14; public static void someMethod() { // implementation not shown } public void someOtherMethod() { // implementation not shown } } Which of the following is a class constant? (2 points)

VALUE1

value2

value3

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

Consider the following incomplete class: public class SomeClass { public static final int VALUE1 = 30; public static int value2 = 10; private int value3 = 5; private double value4 = 3.14; public static void someMethod() { // implementation not shown } public void someOtherMethod() { // implementation not shown } } Which variable is accessible without instantiating a SomeClass object? (2 points)

	VALUE1
	VALUE1 and value2
	value2
	value3
	None of the above

3.

Consider the following incomplete class: public class SomeClass { public static final int VALUE1 = 30; public static int value2 = 10; private int value3 = 5; private double value4 = 3.14; public static void someMethod() { // implementation not shown } public void someOtherMethod() { // implementation not shown } } The method someOtherMethod is NOT defined as static. This means (2 points)

	the method is an accessor method
	the method is accessible outside SomeClass
	the method is not accessible outside SomeClass
	the method is accessible without instantiating a SomeClass object
	the method is accessible only by using a previously instantiated SomeClass object

Consider the following client code and assume that it compiles correctly: public class MainClass { public static void main(String[] args) { SomeClass myObject = new SomeClass(4, 5); int fred = SomeClass.SOME_VALUE; int barney = myObject.method1(); int wilma = SomeClass.method2(4); } } Which of the following is a static method? (2 points)

	method1
	method2
	SomeClass
	SOME_VALUE
	This cannot be determined by examining the above code

What is output by the following code: (2 points) ArrayList< Integer > a = new ArrayList< Integer >(); ArrayList b = a; a.add(new Integer(4)); b.add(new Integer(5)); a.add(new Integer(6)); System.out.println(b.size());

	1
	2
	3
	4
	5

6.

What is output by the following code: (2 points) ArrayList< Integer > a = new ArrayList< Integer >(); ArrayList b = a; a.add(new Integer(4)); b.add(new Integer(5)); a.add(new Integer(6)); a.add(new Integer(7)); System.out.println(b.size());

	1
	2
	3

Consider the following code: ArrayList< Integer > a = new ArrayList< Integer >(); int value; a.add(4); a.add(5); a.add(new Integer(6)); value = a.size(); System.out.println(value); What happens when this code is compiled? (2 points)

	A compiler error occurs on Line 1, because you cannot instantiate an ArrayList in this way.
	A compiler error occurs on Line 3, because you cannot add an int to an ArrayList< Integer >.
	A compiler error occurs on Line 5, because the keyword new is missing when adding an Integer.
	A compiler error occurs on Line 6, because value must be declared as an Integer.
	This code compiles without errors.

8.

Consider the following code: ArrayList < Integer >a = new ArrayList< Integer >(); int value; a.add(4); a.add(5); a.add(Integer(6)); value = a.size(); System.out.println(value); What happens when this code is compiled? (2 points)

	A compiler error occurs on Line 1, because you cannot instantiate an ArrayList in this way.
	A compiler error occurs on Line 3, because you cannot add an int to an ArrayList< Integer >.
	A compiler error occurs on Line 5, because the keyword new is missing when adding an Integer.
	A compiler error occurs on Line 6, because value must be declared as a double.
	This code compiles without errors.

	Any method that invokes super();
	A method that contains a call to itself
