Java解析字符串 [英] Java parsing string

问题描述

我想在java中解析以下字符串

I'm looking to parse the following string in java

<some lines here>
Key1:thingIWantToKnow
Key2:otherThing
Key3:bla
Key4:bla
Key5:bla
<(possibly) more lines here>

所有行都以换行符（\ n）结尾。一旦找到我关心的钥匙，我就想存储价值对。

All lines end with a newline (\n) character. I'm looking to store the value pair once I find the key's I'm care about.

推荐答案

如果地图是什么的你想要：

If a Map is what you want:

Map<String, String> keyValueMap = new HashMap<String,String>();

String[] lines = input.split("\n");
if (lines == null) {
  //Compensate for strange JDK semantics
  lines = new String[] { input };
}

for (String line : lines) {
  if (!line.contains(":")) {
    //Skip lines that don't contain key-value pairs
    continue;
  }
  String[] parts = line.split(":");
  keyValueMap.put(parts[0], parts[1]);
}

return keyValueMap;
