You can create instances of types that are defined as an interface.

	True
	False

2. You are writing a JUnit class to test the constructor of a Rectangle class. The Rectangle class constructor that you are testing looks like this:

public Rectangle(int length, int width){ if (length < 0 || width < 0) { throw new IllegalArgumentException();} this.length = length; this.width = width; }

You write the following test to determine if the class throws an IllegalArgumentException correctly, but you are not sure where you should write a fail command.

@Test public void test02_constructor_exception() { try { Rectangle j = new Rectangle(-1, 3); // line 5 } catch (IllegalArgumentException e) { // line 7 } catch (Exception e) { // line 9 } // line 11 } Choose all of the following places you should add a fail("..."); command to your test.

	line 7
	line 9

	line 5
	line 11

Question 34 pts

In this program below, which lines would lead to compiler errors? Try determine your answers without using Eclipse...then, check your answers in Eclipse.

public class MyOuterClass { private int outer; private class MyInnerClass { private int inner; private MyInnerClass() { inner = 2; } // constructor private void setInner(int s) { inner = s;} }// MyInnerClass public MyOuterClass() { } // constructor public void method1() { MyInnerClass innerObject = new MyInnerClass(); // line 11 innerObject.inner = 12; // line 12 innerObject.outer = 13; // line 13 innerObject.setInner(14); // line 14 inner = 15; // line 15 outer = 16; //line 16 } public static void main(String [] args) { MyInnerClass innerObject = new MyOuterClass(); // line 19 MyOuterClass outerObject = new MyOuterClass(); // line 20 outerObject.method1(); // line 21 } }

Choose all of the following lines that would give a compiler error:

	line 20
	line 15

	line 12
	line 19

	line 21
	line 13

	line 14
	line 11
