javascript call java by java applet

這是要測試，在網頁上嵌入javascript，然後再去call用java寫好的function。

首先我們先從java下手

import java.awt.*;
import java.applet.*;
import javax.swing.*;
import java.io.*;
public class tester1 extends Applet {

  public int hello( int i )
  {
    javax.swing.JOptionPane.showMessageDialog(null, "Hello World!\n i = " + i + ".");
    Graphics g = getGraphics();
    g.drawString("Hello World!\n", 10, 10);
    return i+1;
  }
}
