4. This question involves the process of taking a list of words, called wordList, and producing a formatted
string of a specified length. The list wordList contains at least two words, consisting of letters only.
When the formatted string is constructed, spaces are placed in the gaps between words so that as many spaces as
possible are evenly distributed to each gap. The equal number of spaces inserted into each gap is referred to as
the basic gap width. Any leftover spaces are inserted one at a time into the gaps from left to right until there are
no more leftover spaces.
The following three examples illustrate these concepts. In each example, the list of words is to be placed into
a formatted string of length 20.
Example 1: wordList: ["AP", "COMP", "SCI", "ROCKS"]
Total number of letters in words: 14
Number of gaps between words: 3
Basic gap width: 2
Leftover spaces: 0
Formatted string:

Can you please write the follwing in Java.
You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists.
Use an array of strings to store the 4 strings listed in the description.
Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below:
determine the fruits to display (step 3 below) and print them
determine if there are 3 or 4 of the same image
display the results
update the customer balance as necessary
prompt to play or quit
continue loop if customer wants to play and there's money for another game.
Use the Random class to generate a random number between 0 and 3. This random number will be an index into the array of strings. Add the string at that index to an ArrayList. You'll have to do…

- How can you tell whether the performance of an ArrayList is satisfactory?arrow_forward1. Write a program to input a list of names (strings) from the user and store them in an ArrayList. The input can be terminated by entering the empty string or byentering the string “quit”. 2. Add further functionality to your program so that it searches the ArrayList to find the first string and the last string according to dictionary ordering and then prints out these strings (names). Do this exercise without sorting the names in the ArrayList. For example, if the list contains the following names: Charles Darwin Albert Einstein Issac Newton Tony Hoare Grace Hopper Edgar Dijkstra Ada Lovelace Charles Babbage Stephen Hawking Your program should output:The first name in the list in alphabetical order is: Ada Lovelace The last name in the list in alphabetical order is: Tony Hoarearrow_forward3. Create an ArrayList of strings to store the names of celebrities or athletes. Add five names to the list. Process the list with a for loop and the get() method to display the names, one name per line. Pass the list to avoid method. Inside the method, Insert another name at index 2 and remove the name at index 4. Use a foreach loop to display the arraylist again, all names on one line separated by asterisks. After the method call in main, create an iterator for the arraylist and use it to display the list one more time. See Sample Output. SAMPLE OUTPUT Here is the list Lionel Messi Drake Adele Dwayne Johnson Beyonce Here is the new list * Lionel Messi * Drake * Taylor Swift * Adele * Beyonce Using an iterator, here is the list Lionel Messi Drake Taylor Swift Adele Beyoncearrow_forward
- What happens when you remove the entry from position 4 from a List? Select one: a. All of these b. The entry in the 4th position is returned (if there was a 4th entry) c. If the List has 3 or fewer entries, an IndexOutOfBoundsException is thrown d. If the List has 5 or more entries, the entries in positions 5 and up will move up 1 spot earlier to close up the gap vacated by removing the 4th entryarrow_forwardWrite a Java application CountryList. In the main method, do the following:1. Create an array list of Strings called countries.2. Add "Canada", "India", "Mexico", "Peru" in that order.3. Use the enhanced for loop to print all countries in the array list, one per line.4. Add "Spain" at index 15. Replace the element at index 2 with "Vietnam". You must use the set method.6. Replace the next to the last element with "Brazil". You must use the set method. You willlose one point if you use 3 in the set method. Do this in a manner that would replace thenext to the last element, no matter the size of the array list.7. Remove the object "Canada" Do not remove at an index. Your code should work if"Canada" was at a different location. There is a version of remove method that willremove a specific object.8. Get and print the first element followed by "***"9. Call method toString() on countries to print all elements on one line.10.
