(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 of the following errors occurs, output the appropriate error message and prompt again for a valid data point. If entry has no comma Output: Error: No comma in string.  If entry has more than one comma Output: Error: Too many commas in input.  If entry after the comma is not an integer Output: Error: Comma not followed by an integer.  Ex: Enter a data point (-1 to stop input): Ernest Hemingway 9 Error: No comma in string. Enter a data point (-1 to stop input): Ernest, Hemingway, 9 Error: Too many commas in input. Enter a data point (-1 to stop input): Ernest Hemingway, nine Error: Comma not followed by an integer. Enter a data point (-1 to stop input): Ernest Hemingway, 9 Data string: Ernest Hemingway Data integer: 9 (5) Output the information in a formatted table. The title is right justified with a minimum of 33 characters. Column 1 is left justified with a minimum of 20 characters. Column 2 is right justified with a minimum of 23 characters.  (6) Output the information as a formatted histogram. Each name is right justified with a minimum of 20 characters.  import java.util.Scanner; import java.util.ArrayList; public class DataVisualizer {     public static void main(String[] args) {         Scanner scnr = new Scanner(System.in);         // Prompt the user for a title for data         System.out.println("Enter a title for the data:");         String title = scnr.nextLine();         System.out.println("You entered: " + title);         // Prompt the user for the headers of two columns of a table         System.out.println("Enter the column 1 header:");         String column1Header = scnr.nextLine();         System.out.println("You entered: " + column1Header);         System.out.println("Enter the column 2 header:");         String column2Header = scnr.nextLine();         System.out.println("You entered: " + column2Header);         // Create two ArrayLists to store the string and integer components of the data points         ArrayList dataStrings = new ArrayList<>();         ArrayList dataIntegers = new ArrayList<>();         // Prompt the user for data points         System.out.println("Enter a data point (-1 to stop input): ");         String dataPoint = scnr.nextLine();         while (!dataPoint.equals("-1")) {             // Check for errors in the data point             if (!dataPoint.contains(",")) {                 System.out.println("Error: No comma in string.");             } else if (dataPoint.split(",").length > 2) {                 System.out.println("Error: Too many commas in input.");             } else if (!dataPoint.split(",")[1].matches("\\d+")) {                 System.out.println("Error: Comma not followed by an integer.");             } else {                 // Split the data point at the comma                 String[] dataPointComponents = dataPoint.split(",");                 // Add the string and integer components of the data point to the ArrayLists                 dataStrings.add(dataPointComponents[0]);                 dataIntegers.add(Integer.parseInt(dataPointComponents[1]));             }             // Prompt for the next data point             System.out.println("Enter a data point (-1 to stop input): ");             dataPoint = scnr.nextLine();         }         // Output the information in a formatted table         System.out.println();         System.out.println(String.format("%-33s | %-23s", title, column2Header));         System.out.println("--------------------------------------------");         for (int i = 0; i < dataStrings.size(); i++) {             System.out.println(String.format("%-20s | %23d", dataStrings.get(i), dataIntegers.get(i)));         }         // Output the information as a formatted histogram         System.out.println();         System.out.println("Histogram:");         for (int i = 0; i < dataStrings.size(); i++) {             System.out.println(String.format("%-20s", dataStrings.get(i)) + "*".repeat(dataIntegers.get(i)));         }     }
