- 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: 2 0 1 A A|P| | 3 Basic gap width: 1 Leftover spaces: 2 Formatted string: 0 1 G R Example 2:…arrow_forwardjava Write a program to do the following: Create an ArrayList of Student.

- Write this program in Java using a custom method. Implementation details 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…arrow_forwardComputer Science create a method +addToList(o:E):void that adds the object (o) to the ArrayList referenced by the instance variable list. create a method +removeFromBackOfList():E that removes the object at the back of the ArrayList and returns it.arrow_forwardWhat are wrapper classes and why are they useful for ArrayLists?

- Java 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 a void 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.

The Voter class was used to create instances of Voters which held their name and a voter identification number as instance variables, and the number of instances created as a static variable. This was the class diagram: The constructor takes a string, passed to the parameter n, which is the name of the voter and which should be assigned to the name instance variable. Every time a new voter is created, the static variable nVoters should be incremented. Also, every time a new voter is created, a new voterID should be constructed by concatenating the string “HI” with the value of nVoters and the length of the name. For example, if the second voter is named “Clark Kent”, then the voterID should be “HI210” because 2 is the value of nVoters and 10 is the number…arrow_forwardNedd help in this.

Your method should switch the order of the first two values, then the next two, then the next two and so on. If the number of values in the list is odd, the method should not move the final element.
