Java data structures ,thanks

Bank Account used LinkedList class in Java Instructions: A) Goal: using the existing LinkedList class in java to implement a simple bank account management system, where an existing customer can check his/her balance, perform deposit and withdraw activities and a new customer can open a new account. B) Task: 1) Design an interface named Accountlnteface that contains: (Points: 20/100) a. The accessor and mutator methods for balance, and name, i.e., getName(), getBalance(), setName(String newName) and setBalance(double newBalance) b. A method named withdraw that withdraws a specified amount from the account, i.e, withdraw(double amount) c. A method named deposit that deposits a specified amount to the account, i.e., deposit(double amount) 2) Design an account class to implement the above interface. In this class, you should include a default constructor with name ull and balance-00, and another constructor which can initialize the customer's name and balance (Points: 40/100) (Points: 40/100) 3) Write a TestAccount class that creates an accountList based on LinkedList in java add six customer's accounts into this list including name and initial balance info a. b. C) Procedure: 1. 2. 3. 4. 5. download the attached class TestAccount.java make the mentioned interface Implement the interface Make a linkedList in java to include six customer's info Run the TestAccount
