What will be the output of the following program?
import java.util.*;
public class x {
public static void main(String args[]) {
TreeSet empAgeSet = new TreeSet(new EmployeeComparator_Age());
int i = 0;
int ageDiff[] = {0, -5, 7, 10, -15};
int pinNumber[] = {0, 1, -898, -555, 555, 69};
String[] empNames = {"Dilbert", "Murphy", "Don", "Wattson", "Noddy"};
for (String empName : empNames) {
empAgeSet.add(new Employee1(empName, 30 + ageDiff[i], 1500 + pinNumber[i]));
i++;
}
Iterator empIterator = empAgeSet.iterator();
System.out.print("Name~Age~Pin");
while (empIterator.hasNext()) { System.out.print("\n" + empIterator.next()); }
}
}
class EmployeeComparator_Age implements Comparator {
public int compare(Object emp1, Object emp2) {
Employee1 e1 = (Employee1) emp1;
Employee1 e2 = (Employee1) emp2;
int ret = 1;
if (e1.age == e2.age) ret = 0;
if (e1.age < e2.age) ret = -1;
return ret;
}
}
class Employee1 {
String name;
int age;
int pinNumber;
public Employee1(String n, int a, int s) {
name = n;
age = a;
pinNumber = s;
}
public String toString() { return name + "~" + age + "~" + pinNumber; }
}
