请教java字符串截取的问题

Question

服务器返回的消息
第一种：
{"status":"1","function":"__VoicePrompt"}{"status":"0","function":"__StopNavigation"}
或
{"status":"23","function":"__VoicePrompt"}{"status":"0","function":"__StopNavigation"}

第二种：顺序会变
{"status":"0","function":"__StopNavigation"}{"status":"44","function":"__VoicePrompt"}
或
{"status":"0","function":"__StopNavigation"}{"status":"5","function":"__VoicePrompt"}

我想要的是，把包含__StopNavigation的大括号中的内容去掉，

只保留包含了__VoicePrompt的大括号中的内容--->{"status":"1","function":"__VoicePrompt"}

Answer 1

public static void main(String[] args) {
String str = "{\"status\":\"1\",\"function\":\"__VoicePrompt\"}{\"status\":\"0\",\"function\":\"__StopNavigation\"}";
JSONArray arr = JSONArray.fromObject("["+str.replaceAll("}","},")+"]");
for(int i=0;i<arr.size();i++){
JSONObject temp = arr.getJSONObject(i);
if(temp.containsValue("__StopNavigation")){
arr.remove(temp);
}
}
System.out.println(arr.toString().replaceAll("},","}").substring(1,arr.toString().length()-1));
}
