What is container in spring framework?

Question

1. I was going through this article http://www.vaannila.com/spring/spring-ioc-1.html and here the term container is used. The diagram below shows container. What is contai

Answer 1

Let me explain what the spring container is ..suppose you have a java application with one class named Student and with one variable student name. here we go

public class Student{
 private String name;
 public void setName(String name){
      this.name  = name;
 public void getName(){
      System.out.println("Your Name : " + name);}}

Now you want the name variable should get automatically initialized to iqbal when application runs and the student object should be available inside the main class.

• write an xml configuration file where you will define this Student object.

Now inside the main class we have ApplicationContext

public class MainApp {
   public static void main(String[] args) {
      ApplicationContext context = new ClassPathXmlApplicationContext("Beans.xml");
      Studentobj = (Student) context.getBean("student");
      obj.getMessage();
   }
}

SO please note here ApplicationContext ,this will act as a container and will create and manage the Student class for your application.
