Lottery.java, to generate a lottery of a two-digitnumber. The two digits in the number are distinct. (Hint: Generate the first digit.Use a loop to continuously generate the second digit until it is different from thefirst digit.)
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…

- Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. #include <iostream>using namespace std; int main() { const int NUM_VALS = 4; int courseGrades[NUM_VALS]; int i; for (i = 0; i < NUM_VALS; ++i) { cin >> courseGrades[i]; } /* Your solution goes…arrow_forwardWrite a for loop to print all elements in courseGrades, following each element with a space (including the last).

- My while loop needs help. This is what I have while(!fin.eof()). Something else is expected. Please advise.arrow_forwardYou can check whether a string is a substring of another string by using the find method in the str class. Write your own function to implementfind. Write a program that prompts the user to enter two strings and then checks whether the first string is a substring of the second string.arrow_forwardYou will also have to write Student Tests that test the following in the provided file.i. Adding element(s).ii. Get elements at index – (1) with a valid index and (2) with an invalid indexiii. Test equality of two StringArrayLists (of size 0, 2)iv. Test if a StringArrayList contains a String (test both true and false cases)v.Test removing a String from a StringArrayList.arrow_forward
- What will be the output of Round(3.7).arrow_forwardIn java, please read the text file as array. Then, replace the null with 0 and calculate the sum of the new students in ABC University.Example of text file: (university,year,total_students,new_students,new_staff,ABC, 2000, 3457, , ,ABC, 2001, 3675,218, ,EFG, 2000, 2389,602, ,EFG, 2001, 2785,396, 65,)arrow_forwardWe saw that a merge sort performs roughly the same depending on the type of array we have. For this last exercise, we want to see how the merge sort performs against other sorts. We are using the same two classes that we used a couple of lessons ago. This time the Sorter class has three public methods: mergeSort, insertionSort, and selectionSort. You are also given the SortTester class which has three static methods for creating 3 different types of arrays, random, nearly sorted, and reverse sorted. This test is going to be similar to the previous one, but instead of testing three different types of arrays, you are going to test 3 different types of sorts on the same array type. Create an array using the makeRandomArray method, then take a start time using System.currentTimeMillis(). Next, run the array through the one of the sort methods in the Sorter class. Finally, record the end time and print out the results. You will test each of the 3 sorts. Feel free to also test this with…arrow_forward
