What does the code for this in Java language look like?

For this assignment, you will be writing three classes. One of them is the StudentAccount class that will be used to represent a student account. The account can be used for deposit, charge, and transfer. The other class is for a special type of StudentsAccount which can receive rewards. This class is the RewardsAccount which is a subclass of StudentAccount. RewardsAccount allows an account to receive rewards under certain conditions. For StudentAccount class, you will need to have the variable to represent the account number (acctNo - using long integer type) and balance (using double type) for each account. The variables should be private. The account number will be generated automatically based ona counter. For example, the first account created will have the account number 1, and the one created next will have the account number 2. Therefore, you will also need to have a variable to represent the counter and update this counter accordingly. The counter is not for individual objects; instead it will be shared by the entire class. For RewardsAccount class, you will also have a double variable (rewards) to represent the rewards balance. For all the classes, you will need to decide which variables and methods should be static and which ones should be non-static. 1. StudentAccount class You will need to write the following methods for the StudentAccount class: Constructors All constructors should be defined as "public". .A default constructor should be included. The default balance is set to zero and the account number is automatically generated based on the value of the counter. .A constructor should be included that receives a single double value as a parameter. The parameter will provide the initial balance for the account. Account number will be automatically generated Public Methods getAcctNo- This is a "get" method used to retrieve the account number. getBalance- This is a "get" method used to retrieve the account balance
