從字符串列表中提取元素並將其分配給單獨的字符串

Question

我是 Java 的新手，下面是要求，我有一個像這樣的 JSONArray：

[{"candidate_id":"agent_4","cluster_ID":"To_Be_Added","count":"2","utterance":"Can I text you a confirmation code on the line ending in 1544"}, {"candidate_id":"agent_11","cluster_ID":"To_Be_Added","count":"2","utterance":"Can I text you a confirmation code on the line ending in 3544"}, {"candidate_id":"agent_16","cluster_ID":"To_Be_Added","count":"63","utterance":"Hello Janet can you confirm your phone number?"}

要求是從這個 JSONArray 中一個一個地提取鍵並分配給一個 JSONObject，例如：

{
"candidate_id": "agent_11",
"cluster_ID":"To_Be_Added",
"count":"63",
"utterance":"Can I text you a confirmation code on the line ending in 1544"

} and the rest as well as separate

現在，我將這個 JSONArray 轉換為字符串列表，我將在其中逐一遍歷並提取它：

 for(int j=0;j<s.length(); j++) {
                if(s.contains("candidate_id")){
                    final String candidate_id =exampleList.get(j);
                    logger.info("print  candidate_id={}", candidate_id);
                   
                }

但它沒有提取所需的結果，這里可以做什么？

最終的 Output 應該是這樣的：

Recommendation :{
{candidate_id: "agent_11",
cluster_ID":"To_Be_Added",
count":"63",
"utterance":"Can I text you a confirmation code on the line ending in 1544"
},
{candidate_id: "agent_13",
cluster_ID":"To_Be_Added",
count":"45",
"utterance":"Can I text you a confirmation code on the line ending in 1544"
}}

Answer 1

我相信您在JSONArray中有一個getJSONObject()方法

JSONArray array = new JSONArray()
JSONObject object = array.getJSONObject(0)

您可以遍歷JSONArray並創建JSONObject s
