Variant 3 - Level 2 – Medium.

Your task is to create a prototype of ATM (Automatic Teller Machine).

The following components must be included in your application:

JLabel,

JTextField

JButton

To complete this assessment, you need to implement ATM.java file. The following steps will guide you through this assessment:

1. Explore the screenshot provided below:

2. Run the sample executable by issuing the following command at the command prompt:

C:\>java -jar ATM.jar

3. Next, implement the following program:

In the Textfield “Money” user must enter the amount of money by pressing the Button “Add”. Here, it is important to note, that the minimal amount of money that user can place in his/her account is $100. There must be a check, if user entered correct value. If user will enter a symbol and the amount, which is less than $100, then program must print an Error message.

Note: your initial Balance must be $100.

When you press “Withdraw” button the entered amount must be deducted from Balance amount. Here if Balance is enough, then User receives a message that money was withdrawn successfully. The minimum amount of money that User can withdraw is $10. In case if User will enter less than $10, an error message must be printed out. If User enter the value, which is more than Balance, another error message must be printed out.

Observe how the program responds to the following types of input:

• Enter “a” and press “Place” button;
• Enter 0 and press “Place” button;
• Enter 5 and press “Withdraw” button;
• Enter 150 and press “Withdraw” button;
• Enter “a” and press “Withdraw” button;
