Question

In JAVA: Task 1 Write a program where you create an ArrayList object that can store numbers. Show how you can add a number to the ArrayList, remove a number from the ArrayList, replace a number in the ArrayList, insert a number in a specific location in the ArrayList, and display all the numbers in the ArrayList. Task 2 Create a class named TextProcessing which has the following methodsâ€” (1) getWordsNumber(): This method accepts a string (few sentences long) as an argument and returns the number of words it contains. (2) getVowelsNumber(): This method accepts a string (few sentences long) as an argument and returns the number of vowels it contains. (3) displayBackwardString(): This method accepts a string (few sentences long) as an argument and displays its contents backward. Then write a demo class to work with the TextProcessing class.
