Java 将方法中的数据与另一个方法中的 hashmap 进行比较

Question

此代码正在读取文本文件并创建 HashMap。我想做的是比较我的 ModelOne.txt 和 ModelTwo.txt

中的 StatusMAP 方法

假设我的 ModelOne.txt 有这样的数据：

Model1, 54321, Test, Online

在我的 ModelTwo.txt 上有这样的数据：

Model2, 12345, Check, OFF

我已经知道如何获取文本文件中的索引数据，但我不能做的是基于 StatusMAP 将这两个数据相互比较。所以基本上，如果 ModelOne.txt 与 ModelTwo.txt 比较，它将获得索引 [3]，然后它将比较索引 [3] 在 ModelOne 中是否在线，如果不是，则在 ModelTwo 中应该是 OL，它将将打印 'Not equal' 否则 'They're Equal'.

这篇文章读起来确实很长，但如有任何帮助、建议或评论，我们将不胜感激。提前谢谢大家。

Answer 1

尝试如下，

String data1 = "Model1, 54321, Test, Online";
String data2 = "Model2, 12345, Check, OFF";

String output = (data1.split(", ")[3].equalsIgnoreCase("Online") && 
                 data2.split(", ")[3].equalsIgnoreCase("OL")) ? 
                 "Equal" :
                 "Not Equal";

System.out.println(output);
