1. Consider the following partially complete class:

public class TestClass implements Comparable { private String city; private String state public TestClass( String city, String state ) { this.city = city; this.state = state; } public String getCity() { return this.city; } public String getState() { return this.state; } public int compareTo( Object obj ) { // complete the code here } }

Using the Comparable interface, write a compareTo( ) method that returns -1 if the private instance variable city occurs lexicographically before obj, 0 if the private instance variable city and obj are lexicographically the same, or 1 if the private instance variable city occurs lexicographically after obj. Use a getter method any time you need to use a private instance variable. (6 points)

2. Consider the following partially completed class:

public class SomeClass extends SomeOtherClass { public void convertHours(double hours) { //some code here } public void convertMonths(double months) { //some code here } } }

Write the corresponding abstract class. (4 points)
