NumberDisplay.java

package org.r4r;
import java.util.Scanner;
public class NumberDisplay {
int a,b;
public NumberDisplay(int a, int b) {
super();
this.a = a;
this.b = b;

}
public void display(){
System.out.println("You are enter first number is:-\t"+a);
System.out.println("You are enter second number is:-\t"+b);

NumberTest.java

package org.r4r;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
public class NumberTest {
public static void main(String[] args) {
Resource r=new ClassPathResource("applicationContext.xml");
BeanFactory f=new XmlBeanFactory(r);
System.out.println("Obtaining numbers from the IOC Container...");
NumberDisplay n1=(NumberDisplay)f.getBean("number");
n1.display();
}
}

Output:

Obtaining numbers from the IOC Container...
Enter the first number:-
9876
Enter the second number:-
6789
You are enter first number is:- 9876
