        JOptionpane.showInputDialog("请输入您要翻译的英语!");
        if (english == "select" ) chinese = "选择";   
        else if (english == "result") chinese = "结果";
        else if (english == "width') chinese = "宽度";
        else if (english == 2) chinese = "左边";

        JOptionPane.showMessageDialog(null , chinese);

字符串的都要用equals来表示相等的？？
