Loop keeps writing over textarea

Question

hi everyone, im writing a small application where if a certain word is found in a hashmap, id like it to be printed in a textarea. However, the loop keeps on running a setText method, and im guessing this keeps on writing over the previous text written! i understand why it is doing this, but i just cant think of a solution.
if i run system.out.println on the temp[] variable, the right words are being printed out to the terminal, so its just a matter of transfering these words to the text area.
below is the code for the loop, and also the method addtoarea.
please let me know any suggestions you may have!
thanks alot

     for (int i = 0; i < temp.length; i++) {
if (hashMap.containsKey(temp)) {
          pt.addtoarea(temp[i]);
                    num++;
public void addtoarea (String s)
     area.setText(s);

//Import needed packages.
import javax.swing.*;
import java.util.*;
public class Test extends JFrame
     //create textfield and call the base class construtor
     JTextField area;
     public Test(String str){
     super(str);
     area=new JTextField();
//set Text of the JTextField
public void addtoarea (String s)
               area.setText(s);
public static void main(String[] args)
          //create an object of the Test class
          Test t=new Test("Hi");
          t.setSize(300,300);
          t.setVisible(true);
          t.getContentPane().add(t.area);
          Map hashMap=new HashMap();
          String[] temp=new String[5];
          temp[0]=new String("Hello");
          //check if hashMap contains key if it does set the Text and break out of the loop.
          hashMap.put(0,temp[0]);          
          for (int i = 0; i < temp.length; i++) {
          if (hashMap.containsKey(i))
              t.addtoarea(temp);
          System.out.println(temp[i]);
break;
               i++;
}//end of main
}//end of class TestSwing is not thread safe so you would need to place it in a sepreate thread it would be something of this sort:Runnable doWorkRunnable = new Runnable() {
                    public void run() {
                    ....stuffs
                         SwingUtilities.invokeLater(doWorkRunnable);
