Using bucket search and lookup tables

Question

I have to create an array of dates, and then extend this by creating a lookup table for the months of the dates. So this lookup table will have 12 elements. Finally it should print to the screen the total amount of times a month appears in the object array. I have created my array and i am only working on getting the bucket search working at the moment. In the code you will see the problem i am having on lines 45 and 46. The assigning is of different types so it wont allow it. I was thinking about using a toString method to get this working but then would the lookup tables be able to look up the months still? Also where abouts in the code would i put the toString method? Can i actually do it when declaring the arrays e.g. a[0]=new Date.toSting( (2, "January", 2007) );
Anyway, heres what i have:
import javax.swing.*;
public class Date
public int Day;
public int Year;               
public String Month;
public Date(int day, String month, int year){
Day = day;
Year = year;   
Month = month;
public static void main(String[] args)
final int ARRAY_SIZE = 10;
final int RANGE = 30;
Date[] a = new Date[ARRAY_SIZE];
a[0]=new Date (2, "January", 2007);       
a[1]=new Date (21, "Feburary", 2007);
a[2]=new Date (31, "December", 2007);
a[3]=new Date (29, "Demember", 2007);
a[4]=new Date (8, "April", 2007);
a[5]=new Date (15, "January", 2007);
a[6]=new Date (12, "Feburary", 2007);
a[7]=new Date (30, "August", 2007);
a[8]=new Date (4, "June", 2007);
a[9]=new Date (19, "June", 2007);
boolean result;
String searchKey;
boolean[] bucket = new boolean[RANGE];
for (int i = 0; i < RANGE; i++)
bucket[i] = false;
for (int j = 0; j < ARRAY_SIZE; j++)
String data;
data = a[j]; //???????????????
bucket[data] = true;
searchKey = JOptionPane.showInputDialog("Give me a date");;
result = bucketSearch(bucket, searchKey);
if (result == true)
JOptionPane.showMessageDialog(null,"KEY " + searchKey + " FOUND");
else
JOptionPane.showMessageDialog(null,"KEY " + searchKey + " NOT FOUND");
System.exit(0);
public static boolean bucketSearch (boolean[] bucket, int key)
return bucket[key];
}ps.. i know i need to sort out my searchkey but i will do this after i sort out this problem.
Cheers

The bucket search is actually another question, but i also went to search the net for it and couldnt find anything on bucket search. This is what they are calling a bucket search:
Write a fragment of Java code that does a lookup table search. It asks the user of the program to input a
key to search for and then searches for it in a previously pre-computed lookup table, called bucket that
stores true to mean the data was in the original array and false to mean it was not. It prints a message
indicating whether the data was in the original array or not.
key = Integer.parseInt(JOptionPane.showInputDialog
("Give me a number to search for"));
if (bucket[key] == true)
System.out.print("Data found");
else
System.out.print("Data is not present");
