解决方案
以下示例演示如何使用 AppletContext 类的 showDocument() 方法从小程序转到特定网页。
import java.applet.*;
import java.awt.*;
import java.net.*;
import java.awt.event.*;
public class tesURL extends Applet implements ActionListener {
public void init() {
String link = "yahoo";
Button b = new Button(link);
b.addActionListener(this);
add(b);
}
public void actionPerformed(ActionEvent ae) {
Button src = (Button)ae.getSource();
String link = "http://www."+src.getLabel()+".com";
try {
AppletContext a = getAppletContext();
URL u = new URL(link);
a.showDocument(u,"_self");
} catch (MalformedURLException e){
System.out.println(e.getMessage());
}
}
}
