项目中空指针问题

CustmerList类中：

//修改前
	public Customer[] getAllCustomers() {
		Customer[] customers=new Customer[total];
		for(int i=0;i 
//修改后
	public Customer[] getAllCustomers() {
		Customer[] custs=new Customer[total];
		for(int i=0;i 
CustomerView类中：
 
	Customer[] custs=customerList.getAllCustomers();//获取全部客户
		for (int i = 0; i < custs.length; i++) {//进行循环编号
			Customer cust=custs[i];//第i个数组客户
			System.out.println((i+1)+"tt"+cust.getName()+"t"
					+cust.getGender()+"tt"+cust.getAge()+"tt"
					+cust.getPhone()+"tt"+cust.getEmail());
 
运行后一直显示“Exception in thread “main” java.lang.NullPointerException”，具体到代码中查看。发现由于两个类中变量名不统一导致了空指针异常，已解决
