我收到错误

无效的方法声明，需要返回类型缺少方法主体

private void AutomaticServerConnect()
{
    new Thread(new Runnable() {
        public void run() {
            response = Get(HttpCommandToSend(iptouse, 8098, "nothing"));

            }                
        }).start();
    });

我收到了错误：

}).start();

无效的方法声明，需要返回类型
缺少方法主体

还有一行错误

});

}预期

正确的缩进将帮助您找到无效的大括号：

run

您已关闭Runnable方法，但未关闭匿名private void AutomaticServerConnect() { new Thread(new Runnable() { public void run() { ... } // added } }).start(); } // removed );实例。

应该是：

psql (9.4.5)

forex=# \d pair_data;
                                     Table "public.pair_data"
   Column   |            Type             |                       Modifiers

计算你的花括号。你错过了某个地方的近距离支撑。

这个java方法有什么问题？我在开始时遇到错误
