Design a HTML document that will display the following:

1. A header that reads Please enter your name
2. Two text boxes with labels First Name and Last Name
3. Three radio buttons and a label Gender all in a single row. The labels for the radio buttons will be: Male, Female and Other
4. A button with text Submit

Design a Java servlet program that will:

1. When you enter a first name John, a last name Doe, click on the radio button Male and click on the button Submit, display a response on the webpage Welcome to my shop as a header and a message Thank you Mr. John Doe.
2. When you enter a first name Jane, a last name Doe, click on the radio button Female and click on the button Submit, a response on the webpage will display Welcome to my shop as a header and a message Thank you Ms. Jane Doe.
3. When you enter a first name John, a last name Doe, click on the radio button Other and click on the button Submit, a response on the webpage will display Welcome to my shop as a header and a message Thank you John Doe.

You should consider the following error cases where a message dialogue box should show appropriate message:

1. User doesnt enter text for first name and last name
2. When either a first name or a last name is not entered and the user clicks on the Submit button.
3. When no radio button is checked and the user clicks on the Submit button.

Keep the project aesthetical and creative. Usually this includes user friendly webpage. The look and feel of it. Placing of the components in an appropriate flow. Use of colors and fonts to beautify the presentation. Be creative!!
