Implementation of JSONArray conversion list in java

1: JSONArray to List

JSONArray string to List

//Initialize JSONArrayJSONArray array=new JSONArray();
(0,"a");
(1,"b");
(2,"c");
 
List&lt;String&gt; list = ((),);
 
(());

Output result:
[a, b, c]

JSONArray object to List

//Initialize JSONArrayJSONArray jsonArray = ("[{\"name\":\"zhangsan\",\"age\":18},{\"name\":\"lisi\",\"age\":23}]");
//Print jsonArray(());
//Turn ListList&lt;Body&gt; list = ((), );
//Print List<Body>(());

Code:

/**
 *Test entity class
 **/
static class Body implements Serializable {
        private static final long serialVersionUID = 1L;
        private String name;
        private int age;
 
        public String getName() {
            return name;
        }
 
        public void setName(String name) {
             = name;
        }
 
        public int getAge() {
            return age;
        }
 
        public void setAge(int age) {
             = age;
        }
 
        @Override
        public String toString() {
            return "Body{" +
                    "name='" + name + '\'' +
                    ", age=" + age +
                    '}';
        }
}

Output result:
[{"name":"zhangsan","age":18},{"name":"lisi","age":23}]
[Body{name='zhangsan', age=18}, Body{name='lisi', age=23}]

2: List to JSONArray

List<T> list = new ArrayList<T>();
JSONArray jsonArray = ((list));
