4 个解决方案

#1

You need to add import declarations on class file header.

您需要在类文件头上添加导入声明。

ArrayList is member of java.util package.

ArrayList是java.util包的成员。

And, remember that Java is a case sensitive language. ArrayList is different from Arraylist

并且，请记住Java是一种区分大小写的语言。 ArrayList与Arraylist不同

You should declare like following:

你应该声明如下：

import java.util.ArrayList;

class Bank{
/*class content*/
}

#2

capitalize the L in ArrayList.

在ArrayList中大写L。

#3

It's ArrayList, not Arraylist. Case matters.

它是ArrayList，而不是Arraylist。案件很重要。

#4

Java is case-sensitive. I think the problem is in this line:

Java区分大小写。我认为问题出在这一行：

accounts = new Arraylist();

accounts = new Arraylist（）;

It's "ArrayList" not Arraylist.

它的“ArrayList”不是Arraylist。

I hope to have been helpfull.
