Simple Java code

Suppose you are a regional manager of BP credit card company, and you want to develop a simple

JAVA program that managing the remaining balance for each customer.

Write a simple JAVA program following the direction below:

Create a class Balance that

1) has the following (private) instance variables:

– An integer variable for the customer ID;

A double variable for the remaining balance ($).

2) has the following (public) instance methods:

-Constructor method with two arguments: one for the customer ID, one for the remaining balance

($)

Set the customer ID and the remaining balance ($) to the parameter values;

A method to set the membership ID;

A method to set the remaining balance (5);

A method to retrieve the customer ID-

A method to retrieve the remaining balance ($);

A method to print customer information:

– Print the customer ID and the remaining balance in one line, in a properly aligned format ( use printh).

Create a class Final that has main method.

In the main method, do the followings:

Define array of 100 Balance objects:

Use a loop to read in data from the file. In each iteration, use nextint) to read in the customer ID

and nextDouble0) to read in the remaining balance:

The. Txt file is structured as follows. For simplicity, assume we only have five data points

1001 500

1002 1500

1003 2800

1004 3100

1005 800

The first number for each row is the customer ID and the second number for each row is the remaining balance.

Instantiate array element by using the constructor method to create a Balance object with customer ID and remaining balance retrieved from the given .txt file for each iteration of while loop;

Use a loop to print out all five Balance objects’ information. In each loop iteration, let one array element call the print method.

Use a loop to sum of the remaining balance of all five Balance objects.

Hint: Use the method declared in Balance class

Write the sum of the remaining balance of all five Balance objects (display two decimal places only) into a new file named “output.txt”.

Main method may throw exception. However, we do not want to explicitly handle it. In the method header. throw checked exception (do not use try-catch statements).
