JAVA：遍历多个具有相同名称的 JSON 数组，直到满足内部 JSON 数组的子项条件 - IBM Watson
JAVA: Iterate through multiple JSON arrays with same name until inner JSON array's child's condition is met - IBM Watson
从下面的 JSON 响应中，我需要遍历每个 alternatives JSON 数组中可用的 timestamps直到满足条件（例如：时间为 20 秒和 00 毫秒）。我怎样才能做到这一点？在检查 SO 时，我发现不允许多次使用相同的名称（此处为替代项），但是 JSON 响应是有效的，当它从在线工具验证时（注意：此响应是从 ibm watson speech to文字 API).

你可以试试下面的方法
String s = ""; //Your json string
JSONObject json = new JSONObject(s);
JSONArray jsonArray = json.getJSONArray("results");
Double searchTime = Double.valueOf(0.22);
for(int alt=0 ;alt<jsonArray.length(); alt++){
JSONArray alternatives = jsonArray.getJSONObject(alt).getJSONArray("alternatives");
for(int tmp=0;tmp<alternatives.length(); tmp++){
JSONArray timeStamps = alternatives.getJSONObject(tmp).getJSONArray("timestamps");
for(int t=0;t<timeStamps.length();t++){
if(searchTime.equals(timeStamps.getJSONArray(t).getDouble(1))){
System.out.println(alternatives);
System.out.println(timeStamps.getJSONArray(t));
}
}
}
}
