NumberFactory.java

package org.r4r;
import java.util.Scanner;
public class NumberFactory {
public static NumberDisplay getNumber(){
Scanner in=new Scanner(System.in);
System.out.println("Enter the first number:-");
int x=in.nextInt();
System.out.println("Enter the second number:-");
int y=in.nextInt();
return new NumberDisplay(x,y);
}
}

NumberDisplay.java

package org.r4r;
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);
int x=a+b;
System.out.println("Sum of both number is:-"+x);
}
}

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:-
