ftp客户端什么都不是java

Question

在Android中什么也没显示。

public class Main2Activity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);


        try {
            FTPClient ftpClient = new FTPClient();
            ftpClient.connect(InetAddress.getByName("127.0.0.1"));
            ftpClient.login("android", "98V!");
            System.out.println("status :: " + ftpClient.getStatus());
        } catch (Exception e) {
            e.printStackTrace();
        }
 }

}
