Eclipse 如何在android项目中运行单个文件类进行测试?

Eclipse 如何在android项目中运行单个文件类进行测试?,eclipse,Eclipse,我是android新手。我已经建立了一个项目 我有一个类检查url是否存在,如下所示: public class connect { Boolean checkServer() throws IOException { Boolean check = false; HttpURLConnection connection = null; try { URL url = new URL("www.google.com"); connectio

我是android新手。我已经建立了一个项目

我有一个类检查url是否存在,如下所示:

public class connect {
Boolean checkServer() throws IOException
{
    Boolean check = false;
    HttpURLConnection connection = null;
    try {
        URL url = new URL("www.google.com");
        connection = (HttpURLConnection) url.openConnection();
        connection.connect();
        connection.getInputStream();
                    // do something with the input stream here
        check = true;
    } catch (MalformedURLException e1) {
        e1.printStackTrace();
        check = false;
    }
    finally {
        if(null != connection) { connection.disconnect(); }
    }
    return check;
}
}

我想在eclipse中将其作为单个文件运行

我该怎么做


无论如何谢谢

您可以编写一个Junit类,或者以一种简单的方式,使用public static void main()方法或在同一个类中使用main()方法编写一个新类。您应该创建该类的对象并启动main()方法

publicstaticvoidmain(String[]args)抛出IOException{Boolean check=checkServer();if(check){System.out.println(“thánh công”);}},但当我运行时,它显示消息“aunching遇到了无法连接到vm的问题”,我如何解决这个问题?
public class ConnectDemo {

    /**
     * @param args
     */
    public static void main(String[] args) {

        Connect c = new Connect();

        if(c.checkServer())
            System.out.println("Check Server Successful");
        else 
            System.out.println("Check Server not Successful");
    }

}
