(1) Prompt the user for a title for data. Output the title. Ex:
Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored
(2) Prompt the user for the headers of two columns of a table. Output the column headers. Ex:
Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels
(3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in an ArrayList of strings. Store the integer components of the data points in a second ArrayList of integers.Ex:
Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6
(4) Perform error checking for the data point entries. If any…

Include data fields such as first name, last name, type of relationship, hometown, and age. Include one field that uniquely identifies each record, such as a family member number. You can be creative with the family member number or use the auto-generated number from the database. Populate the database with members of your family. Be sure to include data about yourself in the table. Place at least 10 records in your database table, even if it is necessary to make up information. Write a program to display all of the data that appears in the database table on a data grid.arrow_forward
- 9 All data types processed the same way TRUE FALSEarrow_forward4. Movie Store System This is a system for selling and buying DVDs and videos of movies. There will be three types of users. First the regular customers, they can access the database of DVDs and videos with different types of search. Second there is a group of users that can post DVDs or/and videos to be sold. These users have access to add movies to the database, so that regular customers can search for these movies. When the customer has finished searching for a DVD and/or a video he/she can communicate a message to the seller in order to buy the product from him. The third class of user is the administrator; this user will be in charge of administrating the database and users. The administrator will be in charge of giving and revoking selling privileges to regular customers so that they are able to add videos and DVDs in the database.
