490272 Java: Strings and Collections

STEP 1: Index

Write a Java GUI application called [url removed, login to view] that inputs several lines of text and a search character and uses String method indexOf to determine the number of occurrences of the character in the text.

Sample Program output: View attachment STEP 1

STEP 2: Index2

Write a Java GUI application [url removed, login to view] based on the program in project1 that inputs several lines of text and uses String method indexOf to determine the total number of occurrences of each letter of the alphabet in the text. Uppercase and lowercase letters should be counted together. Store the totals for each letter in an array, and print the values in tabular format after the totals have been determined.

Sample Program output: View attachment STEP 2

STEP 3: ThreeArrayLists (20 points)

Write a program called [url removed, login to view] that declares three arrayLists referenced by the objects named priceList, quantityList, and amountList. Each arrayList should be declared in main() and should be capable of holding a minimum of 10 double-precision numbers.

The numbers that should be stored in price are [url removed, login to view], [url removed, login to view], [url removed, login to view], [url removed, login to view], [url removed, login to view], [url removed, login to view], [url removed, login to view], [url removed, login to view], [url removed, login to view], 3.98.

The numbers that should be stored in quantity are 4, 8.5, 6, [url removed, login to view], 9, 15.3, 3, 5.4, 2.9 4.8.

Your program should pass object references to these three arrays to a method named extend(), which should calculate the elements in the amount array as the product of the corresponding elements in the price and quantity arrays (for example, amount [i] = price[i] * quantity [i]).

After extend() has put values into the amount array, create a method that displays the results of all three lists. Appropriate formatting techniques need to be used to produce a formatted output.

Sample program output:

1) [url removed, login to view] * 4.0 = [url removed, login to view]

2) [url removed, login to view] * 8.5 = [url removed, login to view]

3) [url removed, login to view] * 6.0 = [url removed, login to view]

4) [url removed, login to view] * [url removed, login to view] = [url removed, login to view]

5) [url removed, login to view] * 9.0 = [url removed, login to view]

6) [url removed, login to view] * 15.3 = [url removed, login to view]

7) [url removed, login to view] * 3.0 = [url removed, login to view]

8) [url removed, login to view] * 5.4 = [url removed, login to view]

9) [url removed, login to view] * 2.9 = [url removed, login to view]

10) [url removed, login to view] * 4.8 = 19.1
