从字符串中检索数据

Question

我有这个来自表单的字符串：

   String tmp = "Reason: decision=deny&denyReason=1&denyReasonSubcategory=PoorQuality&subCategoryComments=testsubCategoryComments=subCategoryComments=denyReasonSubcategory=ReviewAgainsubCategoryComments=hellosubCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryComments=subCategoryCommen=&subCategoryComments=&subCategoryComments=&subCategoryComments=&subCategoryComments=";

从上面的字符串中我需要检索：

 denyReason=1
 denyReasonSubcategory=PoorQuality  subCategoryComments=test
 denyReasonSubcategory=ReviewAgain   subCategoryComments=hello

我需要将它们保存如下：

在一个数组中拒绝原因，所以我可以找到相应的值。

休息为：质量差：测试； 再次回顾：你好

我试过以下：

          for (String word : tmp.split("\\&+")){
           if (word.contains("declineReason")){
                System.out.println(word.indexOf("declineReason"));
            // coming as 0
           }
          if (word.contains("declineReasonSubcategory")){
                System.out.println("helloo");
          }
          if (word.contains("subCategoryComments")){
                System.out.println("hii");
          } 
         }
        }

老实说，我已经很久没有像这样处理字符串了，而且对如何获取数据几乎没有迷失。

Answer 1

我会使用扫描仪来提取值。
一台扫描仪提取对。 另一个扫描器来提取该对的值。

看：

import java.util.*;
public class Main{
    public static void main(String[] args) {
      String tmp = "Reason: decision=deny&denyReason=1&denyReasonSubcategory=PoorQuality&subCategoryComments=testsubCategory";
      Scanner s = new Scanner(tmp).useDelimiter("\\&");
      while(s.hasNext()){
         Scanner s2 = new Scanner(s.next()).useDelimiter("=");
         System.out.println(s2.next() + ":" + s2.next());
      }
    }
}
