chNames is an object of type Choice which extends JApplet
Neither Choice or JApplet have a method add(String);
neither have a method named addItemListener()

May be you were thinking of a ComboBox:

CODE

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

public class Choice extends Applet implements ItemListener
{
       TextField txtNames = new TextField(15);
       JComboBox chNames = new JComboBox();

public void init()
{
        chNames.addItem("Naruto");
        chNames.addItem("Sasuke");
        chNames.addItem("Sakura");
        add(chNames);
        add(txtNames);
        chNames.addItemListener(this);
        }

public void itemStateChanged(ItemEvent y) {
            txtNames.setText((String) chNames.getSelectedItem());
        }
}
