- Write a Java program tat prompts user for a list of integers with 0 as the last value.Save the values in an array. Assume there can be maximum 100 values. Theprogram should have the following methods:- A method that takes the array as parameter and updates each value in thearray to the square of the value.- Another method that takes the original and modified arrays as parametersand displays the original and the squared values.True or False? In Java, an array is a primitive type that need not be instantiated.Java Program (Game: ATM machine) Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine. Create 10 accounts in an array with id 0, 1, . . . , 9, and an initial balance of $100. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Thus, once the system starts, it will not stop.
- 1. Create a java program from the supplied starter code: TestRecursion.java.2. The array given can be used or you may input a different one and search for a value in it. YOU MUSThave a minimum of 11 elements in your array if you do not use mine.3. Create a method bubleSortRecur() that performs a bubble sort using recursion. search. The methodaccepts two parameters: an array of integers (any order) and the length. Print the original array, in themain() method after the sort is called.4. Call another method, BinarySearchRecur() that performs binary search recursively. It should take 4parameters: a sorted array of integers, start position (index) and end position(index) of the array, and theinteger value to find. It should return the index of the element if found, if not then it should return -1.Print the one integer being searched, and its index position from within the main() method PLEASE ADD TO THE CODE GIVEN BELOW AND FOLLOW THE SLASHED LINES FOR ASSISTANCE import java.util.Arrays;…in java create a two-dimensional array of type double to contain the three different SD Marks (JD521, PRG521, and IP521) for six different students. A single array of type String must be used to store the student names (Maxwell, Carl, Gerhard, Paul, James, and Cena). Allow a user to enter in a number, ranging from 1 to 6, which will represent the student position in the table MCSD max and present the marks for each respecting module. The program can only stop when the user enter a number greater than 6. Printout the student name including the JD521, PRG521, and IP521 max, the total of marks and the average of all marks. Use a condition statement to decide that the student has passed or not (Pass rate is 70).Question 4 Write Java code for the following: a. Create an Arraylist that can hold Integer objects. b. Check and display whether the Arraylist is empty or not. c. Add an element 50 into the Arraylist. d. Add another element 60 in the position of 0 in the Arraylist. e. Replace the element to 70 in index 1.
- C1. Write a Java program named Occurrence that generates a single-dimensional array of and fill the array with 30 random integer numbers (numbers' range: between 1 and 100 inclusive). The program should display the array elements. Then it should count and display how many odd numbers in the array? A sample run of the program: The array's elements are: 46 24 95 100 3 32 38 89 93 10 70 3 1 13 76 12 95 77 50 55 22 64 83 77 13 94 16 50 41 9 There are 15 odd numbers in the array.Complete the following program ArrayMax.java. The function max() should return a new array containing the max value of each corresponding value in two arrays. Below is the code, with the section that needs to be completed. The output should look exactly like what is given below, alsoBlackjack is a card game where the goal is to reach a score of 21. Create a java version of this game with the following requirements. Extend the JPanel class and create an array of 52 cards. Add four sets of numbers from 1 to 10. Use J for Jack, Q for queen, K for king, and A for ace. Jack through king will have a value of 10, and the ace will have a value of 11. Deal two cards to the user and two cards to the computer. Do not show the value of the computer's first two cards to the user. Add buttons Hit, Stay, and Reset. If the user selects the "Hit" button, randomly select one of the cards from the array, and give it to the user. (After selecting a card, do not reuse this index during the rest of the game.) If the dealer has less than 21, "hit" the dealer, too. When the user selects the "Stay" button, add up the card values. The winner is the person who is closest to 21 without going over. Name the class Blackjack.java.
- RU Rotten Tomatoes . Write a program RURottenTomatoes.java that creates a 2 dimensional integer array of movie ratings from the command line arguments and displays the index of the movie that has the highest sum of ratings. Ratings range from 1 to 5 (inclusive). The rows of the 2D array correspond to movie reviewers and the columns of the 2D array correspond to movies. The reviewer at index 2 gave movie at index 0 a rating of 4. Take a look at the following example for an explanation on the command line arguments sequence. java RURottenTomatoes 3 2 5 2 3 3 4 1 0 1 0 5 2 1 3 3 2 4 1 The first argument corresponds to the number of reviewers and the second argument corresponds to the number of movies (the dimensions of the 2D integer array). Following are the movie ratings in a row-major order.…TASK 3 Write a Java method that returns the location of the largest element in a two-dimensional array. public static int[] locatelargest(double[][] a) The return value is a one-dimensional array that contains two elements.
