如何将布尔代码更改为java中的int代码

我试图在我的管理面板中更改一些代码，因为我的协议中有一些最近的更改。我想要做的是将代码从布尔值更改为int。我会说现在我是一个完全新手，在Java中如此裸露。如何将布尔代码更改为java中的int代码

旧协议：公共静态布尔GMSetDoubleExp（布尔）

这里是原代码：

try 
        { 
         String dblexp_on = request.getParameter("dblexp_on"); 
         if(dblexp_on == null){dblexp_on = "false";} 
         if(DeliveryDB.GMSetDoubleEXP(dblexp_on.equals("true"))) 
         { 
          //message += "<font color=\"#00cc00\"><b>Saved Double Experience Points</b></font><br>"; 
         } 
         else 
         { 
          //message += "<font color=\"#ee0000\"><b>Saving Double Experience Points Failed</b></font><br>"; 
          message = "<font color=\"#ee0000\"><b>Saving of one or more Values Failed<b></font>"; 
         } 
        }

新的协议：公共静态布尔GMSetDoubleExp（INT）

这里是代码我现在有：

try 
        { 
         int dblexp_on = Integer.parseInt(request.getParameter("dblexp_on")); 
         if(dblexp_on == 0){dblexp_on = (0);} 
         if(DeliveryDB.GMSetDoubleExp(dblexp_on = (1))) 
         { 
          //message += "<font color=\"#00cc00\"><b>Saved Double Experience Points</b></font><br>"; 
         } 
         else 
         { 
          //message += "<font color=\"#ee0000\"><b>Saving Double Experience Points Failed</b></font><br>"; 
          message = "<font color=\"#ee0000\"><b>Saving of one or more Values Failed<b></font>"; 
         } 
        }

即使我没有错误当运行该页面时，它会给我一条错误消息，说明它尚未保存。任何人有什么想法，我做错了什么？

int对于这样的任务并不是很好。您可以尝试[enum]（http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html）。 – lifus

请提供有关'DeliveryDB.GMSetDoubleExp'的更多详细信息。实际上应该做什么以及在什么条件下？ –

@ lifus - 已经被'Joan'（见下文）提出，并被OP看似承认。 –

运营商同等比较 - 是==你的代码应该是：

if(DeliveryDB.GMSetDoubleExp(dblexp_on == (1)))

=是分配操作

如果GMSetDoubleExp方法需要一个整数，那么你应该使用：

if(DeliveryDB.GMSetDoubleExp(dblexp_on))

我给它去了，但它向我扔了一个错误类型DeliveryDB中的方法GMSetDoubleExp（int）不适用于参数（布尔值） –

好吧，那么你只需要使用'DeliveryDB.GMSetDoubleExp（dblexp_on ）'因为dblexp_on是一个整数。 – Joan

我刚刚尝试过，它没有给出任何错误，但它仍然没有保存它并注册为“on” –

@damadbo y：@ +1与@Joan。此外，不要将整个逻辑从布尔型更改为整型，而是可以编写一个自定义函数，该函数将输入为布尔型字符串并返回其int类型。这样，它减少了代码的麻烦，并且使调试更容易。该功能将如下所示。

private int flagConverter(String flag) { 
     if(flag.equalsIgnoreCase("true")) 
      return 1; // returns 1 on TRUE 
     else if(flag.equalsIgnoreCase("false")) 
      return 0; // returns 0 on FALSE 
     else 
      return -1; // returns -1 for any inappropriate input 
    }

尝试此操作时出现不少错误。我可能使用它错误，但这些是我得到的错误： '错误发生在行：145在jsp文件中：/server.jsp 变量flagConverter的非法修饰符;只有最后一次被允许 jsp文件中的行：145处发生错误：/server.jsp 令牌“（”，;;预期的语法错误在jsp文件：/ server中，在行：145处发生错误。 jsp 令牌上的语法错误“）”，;预期' –
