java - 如何分割所需格式的字符串？

Question

我有以下文本格式

 String s = "
 key1:value1;
 key2:value2;
 key3:value3;
 key4:value4;
 key5:value5;
 key6:https://url1.com, https://url2.com;
 key7:value;";
 Note: (the number of urls in key6 will be 1 to many and non linear)

我使用 S.split(";") 将 s 拆分为 7 个键值 block

 String keyValPair[] =  s.split(";");
  Output will be
  /* keyValPair[0] contains key1:value
     keyValPair[1] contains key2:value
     keyValPair[2] contains key3:value and 
     keyValPair[6] contains key6:https://url1.com,https://url2.com;

现在我想再次分别拆分键和值并将其存储在数组 0 和 ist 位置中。

     //while looping into keyValPair[i]
     String[] singleKeyVal[] = keyValPair[0].split(":");
     /*Output
         singleKeyVal[0] will have Key1
         singleKeyVal[1] will have Value1
          perform some task and clear the array singlekeyVal[] 

问题是如何正确拆分Key6

 //while looping into KeyValPair[i]
 String[] singleKeyVal[] = keyValPair[5].split(":");  //6th chunk contains : in the URL too
 /*Output
     singleKeyVal[0] will have Key6
     singleKeyVal[1] should contain https://url1.com,https://url2.com
     also note that above example contains only 2 urls but it will contain urls between 1 to many urls,

Answer 1

有两种 split 方法 - the second one 采用 limit 参数，允许您指定所需的最大组数。对于您的情况:

String[] singleKeyVal = keyValPair[5].split(":", 2);

应该做你想做的事。

ps:您应该采用Java命名约定(变量以小写开头)。
