Main.java

This is the file through which we are retrieving the property of the bean defined above. Some of the methods which are used here are as follows:-

XmlBeanFactory factory = new XmlBeanFactory(new ClassPathResource("context.xml")):-This method creates an instance of the XmlBeanFactory which is used to read bean definition from an XML document

new ClassPathResource("context.xml"):-Creates a new ClassPathResource for ClassLoader .Here the context.xml is the file which is to be loaded.

(bf.getBean("child")):-This method returns an instance of the bean named "child", which is shared or independent, of the given bean name.

(bf.getBean("subchild")):-This method returns an instance of the bean named "subchild", which is shared or independent, of the given bean name.

stringBuilder.append("Bean"):-This is the method of the class string Builder which appends the specified string to this character sequence.

import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;

public class Main {
  public static void main(String[] args) throws Exception {
  XmlBeanFactory bf = new XmlBeanFactory(new ClassPathResource("context.xml"));
  System.out.println("===============Inheritance demo=================");
  System.out.println(bf.getBean("child"));
  System.out.println(bf.getBean("subchild"));
  
  }
}
class mybean {
  private String name;
  private String address;

  public void setName(String name) {
  this.name = name;
  }

  public void setAddress(String address) {
  this.address = address;
  }
 
  @Override
  public String toString() {
  final StringBuilder stringBuilder = new StringBuilder();
  stringBuilder.append("Bean");
  stringBuilder.append("{name='").append(name).append('\'');
  stringBuilder.append(", address=").append(address);
 
  stringBuilder.append('}');
  return stringBuilder.toString();
  }
}
