Question

我是Java的初学者，我正在尝试构建一个聊天机器人。查询和响应在2D字符串数组chatbot [] []中进行硬编码。

这是我使用的完整代码，已经使用了两个用于JTextArea'输入和对话'的对象。对象输入已附加到JPanel，用于从用户获取文本，然后在2D字符串数组中搜索。如果找到，则从同一数组中抛出响应。

现在我的要求是当响应是任何URL时，它应该显示为链接，以便用户可以直接点击并转到该站点（http://google.com以获取当前场景）。建议如何实现这一点。或者需要对代码进行任何修改。 addText是定义为将整个会话添加到不可编辑的对话文本区域的方法。

JFrame j=new JFrame("Temenos ChatBot");
JPanel p=new JPanel();
JTextArea dialog=new JTextArea(20,50); //it will contain the whole conversation(non editable)
JTextArea input=new JTextArea(1,50); //where we user input our query(editable)

    dialog,

String[][] chatbot={

Answer 1

您可以使用Uri的解析静态方法

Uri myUri = Uri.parse("http://google.com")

Answer 2

如果你正在制作一个GUI，你可以跟随另一个堆栈溢出答案，例如这个 How to add hyperlink in JLabel

或者，您可以让java打开浏览器到该网页：

 // Create Desktop object
 Desktop d=Desktop.getDesktop();
 // Browse a URL, say google.com
 d.browse(new URI("http://google.com"));
