Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'college' available

my tested code

package com.annotations.annotations;

import org.springframework.stereotype.Component;

@Component("college") public class College {

public void id() {
    System.out.println("33");
}

@Configuration public class Config {

@Bean
public College name() {
    return new College();
}

}



import javax.naming.Context;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;


public class App 
{
    public static void main( String[] args )
    {
     ApplicationContext mech=new AnnotationConfigApplicationContext(Config.class);
    
     College lokesh=mech.getBean("college",College.class);
     lokesh.id();
     
     
}

I am getting error like this

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'college' available at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:872) at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1344) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:309) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:213) at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1160) at com.annotations.annotations.App.main(App.java:15)

You must specify the bean name

@Bean(name = "college")
public College name() {
    return new College();
}
