Using for-each loop I got all the key value from jsonObj, and finally using that key I got the corresponding value.  Finally I got the alert like this,    Key: a value:10    Key: b value:20    Key...

In spring application, you have two ways for injecting beans. These are,  1. Setter based injection.  2. Constructor based injection. You can able to use primitive type as well as reference type for injecting. Example for setter based injection. In this example I am going to inject the room object into home using setter method. 1.  Create a new Room bean like this.      package com.setterinject;      public class Room {         private String roomName ;          public String getRoomName() {             return roomName ;        }          public void setRoomName(String roomName) {             this . roomName = roomName;        }      } 2 .Create a new Home bean POJO ...
