need help displaying an ordered array list by count

[Brent Geeeee]

i got a program that stores words and counts the number of occurences of that word and im trying to print them from an arraylist

it just displays Chapter18.CountingOccurences
[Chapter18.WordOccurence@26e431, Chapter18.WordOccurence@14f8dab, Chapter18.WordOccurence@1ddebc3, Chapter18.WordOccurence@a18aa2, Chapter18.WordOccurence@194ca6c, Chapter18.WordOccurence@17590db, Chapter18.WordOccurence@17943a4, Chapter18.WordOccurence@480457, Chapter18.WordOccurence@14fe5c, Chapter18.WordOccurence@47858e, Chapter18.WordOccurence@19134f4, Chapter18.WordOccurence@2bbd86, Chapter18.WordOccurence@1a7bf11, Chapter18.WordOccurence@1f12c4e]

but i want to do it so it displays the word and the count

import java.util.*;

public class CountingOccurences
{
public static void main(String [] args)
{
String text = "Have a good day, Have a good class. " +
"Have a good visit. Have fun!";

Map hashMap = new HashMap();
List arrayList = new ArrayList();

StringTokenizer st = new StringTokenizer(text, " .!?");

while (st.hasMoreTokens())
{
String key = st.nextToken();

if(hashMap.get(key) != null)
{
int value = ((Integer)hashMap.get(key)).intValue();
value++;
hashMap.put(key, new Integer(value));
}
else
{
hashMap.put(key, new Integer(1));
}
arrayList.add(new WordOccurence(key, ((Integer)hashMap.get(key)).intValue()));
}

Collections.sort(arrayList);

System.out.println(arrayList);


}
}

public class WordOccurence implements Comparable
{

String word;
int count = 0;

public int compareTo(Object o)
{
if (this.count == ((WordOccurence)o).count)
{
return 0;
}
else if (this.count > ((WordOccurence)o).count)
{
return 1;
}
else
{
return -1;
}
}

public WordOccurence(String word, int count)
{
this.word = word;
this.count = count;
}
}

Hi,

From a brief look at your code it seems that you are just printing out the arraylist, which is a list of objects. This means the output you are getting is correct.

To produce the output you want you would have to loop through the ArrayList pulling calling the attributes from each object pulled back.

Hope that helps,

John

Hi,

you should override toString() in class word occurence:
eg

public String toString(){
String out = this.word;
out += ": ";
out += this.count;
     return out;
}

Yours,
Bu.
