Sharing an array between methods

Question

I have three classes as follows
import javax.swing.*;
public class result
String names, date, scores, records;
public result(String na, String da, String sc)
     names=na;
     date=da;
     scores=sc;
public String getName()
        return names;
public String getDate()
        return date;
public String getScore()
        return scores;
import javax.swing.*;
public class resultList 
final int DEFAULT_SIZE = 20;
int count;
result[] data;
public resultList()
data = new result[DEFAULT_SIZE];
count = 0;
public resultList(int size)
data = new result[size];
count = 0;
public void insert( result  myResults )
data[count] = myResults;
count++;
public result[] getResult()
return data;
import javax.swing.*;
import java.util.*;
import java.io.*;
public class Sport
public static void main (String[] args)
boolean alive = true;
try     
while (alive)
String menu = JOptionPane.showInputDialog(   //This the menu the user see's
"Select 1 to input results\n"+
"Select 2 to linearsearch\n"+
"Select 3 to Check contents of  array\n"+
"Select 0 to Quit");
int menu2=Integer.parseInt(menu);
if (menu2==1)           //i use if statements to match the methods with the menu
inputteams();
if (menu2==2)
linearsearch();
if (menu2==3)
printArray();
if (menu2==0)
alive = false;
catch (IOException e)
System.err.println("Caught IOException: "+ e.getMessage());
public static void inputteams()throws IOException
resultList myList = new resultList();
int count = 0;
int stillContinue = JOptionPane.YES_OPTION;
while (stillContinue == JOptionPane.YES_OPTION)
String na = JOptionPane.showInputDialog("Please, enter team name");
String da = JOptionPane.showInputDialog("Enter date:");
String sc = JOptionPane.showInputDialog("Please enter score");
if (na!=null && da!=null && sc!=null)
result data = new result(na, da, sc);
myList.insert(data);
else
JOptionPane.showMessageDialog(null,"Please enter all required data");
stillContinue = JOptionPane.showConfirmDialog(null, "Enter another record?",
"???", JOptionPane.YES_NO_OPTION);
count++;
public static void printArray() 
resultList myList = new resultList();
result[] data = myList.getResult(); 
for( int i=0; i<data.length; i++)
result myResults = data;
if( myResults != null )
System.out.println("Database contents" + myResults.toString());
else
System.out.println("232"); //Handling empty elements in the array
}               //to avoid return of nullPointer
}When i run the program and the menu pops up, i enter one and start inputting data.  Once i have completed this the menu pops up again.  This time i choose 3 to print the contents of my array.  However, all this does is print 232 numerous times which shows that the array i am creating in my printArray() is not being passed the contents of my array.  I have used a similar procedure to what i am doing in a different rpogram and it seems to work.  I cant see why this time the contents of my filled up array isnt being passed to this method.  Any advice on where i am going wrong?
