如何在Java中将字符串显示为URI

Question

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

这是我使用过的完整代码，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上，用于从用户那里获取文本，然后在2D字符串数组中进行搜索，如果找到，则从同一数组引发响应。

现在我的要求是，当响应为任何URL时，都应将其显示为链接，以便用户可以直接单击并转到该站点（对于当前方案为http://google.com ）。请提出如何实现此目标或需要对代码进行任何修改。 addText是定义为将整个对话添加到不可编辑的对话文本区域的方法。

import java.awt.event.KeyListener; 
import java.awt.event.KeyEvent;

import java.awt.Toolkit;

public class test implements KeyListener{

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)
JScrollPane scroll=new JScrollPane( 
    dialog,
    JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
    JScrollPane.HORIZONTAL_SCROLLBAR_NEVER

String[][] chatbot={

{"hi","hello","hola","ola","howdy"}, //check for query
{"hi","hello","hey"}, //provides output of the query

{"google","provide link for google","www.google.com"}, //Query

Answer 1

您可以使用Uri中的静态解析方法

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

Answer 2

如果您要制作一个摆动的GUI，则可以遵循另一个堆栈溢出答案，例如此方法如何在JLabel中添加超链接

或者，您可以只用Java打开该网页的浏览器：

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