JAVA 從數組中取值，塞進另壹個新建數組中

import?java.util.Arrays;

import?java.util.List;

import?net.sf.json.JSONObject;

public?class?$?{

public?static?void?main(String[]?args)?{

List<JSONObject>?data?=?new?ArrayList<JSONObject>();

initData(data);

Integer[]?arr?=?new?Integer[data.size()];

int?idx?=?0;

for?(JSONObject?jsonObject?:?data)?{

arr[idx++]?=?jsonObject.getInt("高");

}

System.out.println(Arrays.deepToString(arr));

}

private?static?void?initData(List<JSONObject>?data)?{

//?這裏全是半角

data.add(JSONObject.fromObject("{'長':'100','寬':'100','高':'100'}"));

data.add(JSONObject.fromObject("{'長':'100','寬':'100','高':'101'}"));

data.add(JSONObject.fromObject("{'長':'100','寬':'100','高':'102'}"));

data.add(JSONObject.fromObject("{'長':'100','寬':'100','高':'103'}"));

data.add(JSONObject.fromObject("{'長':'100','寬':'100','高':'104'}"));

data.add(JSONObject.fromObject("{'長':'100','寬':'100','高':'105'}"));

}

}
