　　四、遍历JSON实例
　　以上面的输出的JSON字符串进行按顺序给它遍历
　　String ClassName1 = (String) container1.get("ClassName");
　　System.out.println("ClassName data is: " + ClassName1);
　　JSONArray className1 = container1.getJSONArray("className");
　　System.out.println("className data is: " + className1);
　　JSONObject classInfo1 = container1.getJSONObject("classInfo");
　　System.out.println("classInfo data is: " + classInfo1);
　　JSONObject ClassInfo1 = container1.getJSONObject("ClassInfo");
　　System.out.println("ClassInfo data is: " + ClassInfo1);
　　JSONArray students1 = container1.getJSONArray("students");
　　System.out.println("students data is： " + students1);
　　JSONArray Students1 = container1.getJSONArray("Students");
　　System.out.println("Students data is: " + Students1);
　　JSONArray teachers1 = container1.getJSONArray("teachers");
　　for(int i=0; i < teachers1.size(); i++){
　　System.out.println("teahcer " + i + " is: "+ teachers1.get(i));
　　}
　　JSONArray Teachers1 = container1.getJSONArray("Teachers");
　　for(int i=0; i < Teachers1.size(); i++){
　　System.out.println("Teachers " + i + " is: "+ Teachers1.get(i));
　　}
　　遍历结果：
　　ClassName data is: 高三一班
　　className data is: ["高三一班"]
　　classInfo data is: {"stuCount":50，"leader":"rah"}
　　ClassInfo data is: {"stuCount":[50]，"leader":["rah"]}
　　students data is： [{"name":"张麻子"，"sex":"男"，"age":12，"hobby":"java develop"}，{"name":"王瘸子"，"sex":"男"，"age":13，"hobby":"C/C++ develop"}]
　　Students data is: [{"name":["张麻子"]，"sex":["男"]，"age":["12"]，"hobby":["java develop"]}，{"name":["王瘸子"]，"sex":["男"]，"age":["13"]，"hobby":["C/C++ develop"]}]
　　teahcer 0 is: 王老师
　　teahcer 1 is: 李老师
　　Teachers 0 is: {"name":"小梅"，"introduce":"他是一个好老师"}
　　Teachers 1 is: {"name":"小李"，"introduce":"他是一个合格的老师"}
　　上面包括了大部份的JSON的嵌套形式，可能有忽略的也可以参考上面的内容。
