CustomerView类的实现：

public class CustomerView {
        
    	public static void main(String[] args) {
        
    		CustomerView custView = new CustomerView();
    		custView.enterMenu();
    	}
    	
    	//属性
    	private CustomerList customerList = new CustomerList(10);//实例化一个CustomerList对象，数组长度为10
    													 //数组长度是CustomerList的属性customers
    	
    	//构造器
    	public CustomerView() {
        
    		//在实例化时初始化一个Customer对象添加到CustomerList（customerList）中
    		Customer cust = new Customer("Jony", '男', 18, "18238899465", "Google@163.com");
    		customerList.addCustomer(cust);
    	}
    	//方法
    	/**
    	 * 程序界面进入方法
    	 */
    	public void enterMenu() {
