（1）下边的一个java类包括了全部Map、Set、List、数组、属性集合等这些容器，主要用于演示Spring的注入配置；

package com.lc.collection;

import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

public class Department {

	private String name;
	private String [] empName;//数组
	private List<Employee> empList;//list集合
	private Set<Employee> empsets;//set集合
	private Map<String,Employee> empMaps;//map集合
	private Properties pp;//Properties的使用

	
	public Set<Employee> getEmpsets() {
		return empsets;
	}
	public void setEmpsets(Set<Employee> empsets) {
		this.empsets = empsets;
	}
	public String[] getEmpName() {
		return empName;
	}
	public void setEmpName(String[] empName) {
		this.empName = empName;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public List<Employee> getEmpList() {
		return empList;
	}
	public void setEmpList(List<Employee> empList) {
		this.empList = empList;
	}
	public Map<String, Employee> getEmpMaps() {
		return empMaps;
	}
	public void setEmpMaps(Map<String, Employee> empMaps) {
		this.empMaps = empMaps;
	}
	public Properties getPp() {
		return pp;
	}
	public void setPp(Properties pp) {
		this.pp = pp;
	}

}

（3）怎样使用
package com.lc.collection;

import java.util.Enumeration;
import java.util.Iterator;
import java.util.Map;
import java.util.Properties;
import java.util.Map.Entry;

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

public class App1 {

	
	public static void main(String[] args) {

		ApplicationContext ac=new ClassPathXmlApplicationContext("com/lc/collection/beans.xml");
		Department department=(Department) ac.getBean("department");
		System.out.println(department.getName());
		for(String emName:department.getEmpName()){
			System.out.println(emName);
		}
		/*
		 * 通过list集合取出数据
		 */
		System.out.println("**********通过list集合取出数据*****");
		for(Employee e : department.getEmpList()){
			System.out.println("name="+e.getName()+" "+e.getId());
		}
		/*
		 * 通过set集合取出数据
		 */
		System.out.println("**********通过set集合取出数据*****");
		for(Employee e : department.getEmpsets()){
			
			System.out.println("name="+e.getName());
		}
		/*
		 * 通过map集合取出数据 迭代器
		 */
		System.out.println("*******通过map集合取出数据 迭代器****");
		
		//1.迭代器
		Map<String,Employee> empmaps=department.getEmpMaps();
		Iterator it=empmaps.keySet().iterator();
		while(it.hasNext()){
			String key=(String) it.next();
			Employee emp=empmaps.get(key);
			System.out.println("key="+key+" "+emp.getName());
		}
		
		System.out.println("*******通过map集合取出数据 简洁方法****");
		//2.简洁方法
		for(Entry<String,Employee> entry1:department.getEmpMaps().entrySet()){
			
			System.out.println(entry1.getKey()+" "+entry1.getValue().getName());
		}
		
		System.out.println("*****通过Propertis取出数据*****");
		Properties pp=department.getPp();
		for(Entry<Object,Object> entry:pp.entrySet()){
			System.out.println(entry.getKey().toString()+" "+entry.getValue().toString());
		}
		System.out.println("*****通过Enumeration取出*****");
		Enumeration en= pp.keys();
		while(en.hasMoreElements()){
			String key=(String) en.nextElement();
			System.out.println(key+" "+pp.getProperty(key));
		}
	}

}


（4）以后那些不知道的粘贴拷贝就可以
