Question

json数据中有json数组 怎么解析

Answer 1

实例：
import net.sf.json.JSONArray;

public class TestJson
{
public static void main(String []args)
{
String json = "[{\"a\":\"111\",\"b\":\"222\",\"c\":\"333\"},{\"a\":\"1000\",\"b\":\"2000\",\"c\":\"000\"},{\"a\":\"999\",\"b\":\"300\",\"c\":\"700\"}]";
JSONArray jsonArr = JSONArray.fromObject(json);
String a[] = new String[jsonArr.size()];
String b[] = new String[jsonArr.size()];
String c[] = new String[jsonArr.size()];
for (int i = 0; i < jsonArr.size(); i++) {
a[i] = jsonArr.getJSONObject(i).getString("a");
b[i] = jsonArr.getJSONObject(i).getString("b");
c[i] = jsonArr.getJSONObject(i).getString("c");
}

for (int i = 0; i < c.length; i++) {
System.out.print(a[i]+" ");
System.out.print(b[i]+" ");
System.out.print(c[i]);
System.out.println();
}
}
}
