    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

        <bean id="collectionDemo" class="com.prashant.Collections6.CollectionDemo">
                <constructor-arg index="0" type="String" value="google"/>
                <constructor-arg index="1" type="String" value="gooogle"/>
        </bean>

    </beans>

CollectionDemo.java

public class CollectionDemo<T> {
    private T id,phoneNumber;

    public CollectionDemo(T id, T phoneNumber) {
        super();
        this.id = id;
        this.phoneNumber = phoneNumber;
    }

    public T getId() {
        return id;
    }

    public void setId(T id) {
        this.id = id;
    }

    public T getPhoneNumber() {
        return phoneNumber;
    }

    public void setPhoneNumber(T phoneNumber) {
        this.phoneNumber = phoneNumber;
    }

    @Override
    public String toString() {
        return "CollectionDemo [id=" + id + ", phoneNumber=" + phoneNumber
                + "]";
    }

ColleactionApp.java

package com.prashanth.Collections6;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class ColleactionApp {
    public static void main(String[] args) {
        ApplicationContext app=new FileSystemXmlApplicationContext
        ("/src/main/java/com/prashanth/Collections6/beans.xml");
        CollectionDemo<String> coll=(CollectionDemo<String>) app.getBean("collectionDemo");
        System.out.println(coll);
    }
}
