- Given an array of numbers, and an integer, find the last index that that integer appears in the array. If the number is not found, return -1. import java.util.ArrayList;public class LastIndexFound{public static int solution(ArrayList<Integer> nums, int numToFind){// ↓↓↓↓ your code goes here ↓↓↓↓return 0;}}Write code that will accept as input the characteristics of an undefined number of different softdrinks. Each softdrink should have a colour (of the can), name and volume. • Create SoftDrink objects and store them in an ArrayList (see the Appendix) as each softdrink is entered. • Alternatively, you can use an array. Take a number of items first, create an array of that size and read in the elements. • Prompt the user to add a softdrink until they choose to quit. • Once the user quits, print out a list of the softdrinks that the user has entered, sorted first by alphabetical order of name, then by colour, then by volume (ascending order). Name your driver class Question2.java. NOTE: • You can use the built-in static sort() method in the java.util.Collections class to sort your ArrayList of SoftDrink objects. Sample I/O Enter option: (1) add soft drink (2) quit: 1 Enter name, colour and volume in ml separated by space Fanta Orange 500 Enter option: (1) add soft drink (2)…Provide a code segment that creates an arraylist of three integers and prints these values on the screen. Then add two more integers and print out the last integer on the screen. Note: You are free to choose integers.
- Write a java application which initializes an array with ten random integers between 1 and 6. Write two methods: 1. arraySwap: this method should accept an integer array and swap the first and the last item. 2. findMinimum: this method should accept the array and return the minimum value of that array You should comment and follow javaDoc for both methods. Your main method should test each of these methods.Write a Java class, XXX_Lab71, where XXX is your Kean email ID. The classwill do the following:1) Create an Array which can contain 5 elements using an initializer list.2) The values in the list will be: 11, 22, 33, 44, 553) Using an assignment statement, change the element at index position,3, to 88.4) Print the elements of the array from first to last using a loop. Use thelength property to print the elements.5) Print the elements of the array from last to first using a loop. Use thelength property to print the elements.in java Create two arrays with same length n: - Array A with integer numbers that user will insert- Array B with random numbers from 0 to 100.- Find sum of both arrays,- Find maximum values of both array and compare them: .if maximum of 1 st is lower then maximum of 2nd array: print sums of both arrays.if maximum of 1st is greater then maximum of 2nd array print 2nd array (use println)otherwise print first array in reverse.
- Programming exercise (in java eclipse, please add comments for each step). Write a complete Java program named FindProduct that contains the following: a. A main method asks the user to provide the number of rows and columns for a 2-dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printProduct method that will: i. Receive the two-dimensional array as input ii. Calculate the product of elements in each row of the array iii. Display the product on the Console. The product of all elements in each row should be formatted as "Row 1 Product XXXX"please use the name, phonenumber and phonebookentry to build this. The three parallel arrays are gone — replaced with a single array of type PhonebookEntry. You should be reading in the entries using the read method of your PhonebookEntry class (which in turn uses the read methods of the Name and PhoneNumber classes). Use the equals methods of the Name and PhoneNumber classes in your lookup and reverseLookup methods. Use the toString methods to print out information. Make 100 the capacity of your Phonebook array Throw an exception (of class Exception) if the capacity of the Phonebook array is exceeded. Place a try/catch around your entire main and catch both FileNotFoundExceptions and Exceptions (remember, the order of appearance of the exception types in the catch blocks can make a difference). Do not use BufferedReader while(true) breaks The name of your application class should be Phonebook. Also, you should submit ALL your classes (i.e., Name, Strip off public from all your class…Write only the required Java statements to do the following: i) create a new ArrayListobject named cityList to hold String objects; ii) add the following city names (as string) in the array list: Atlanta, Chicago, Denver, Houston, Minneapolis; iii) remove the item at index 3 and then print the item stored at index 3 of cityList. iv) What value will be printed for index 3?
- . Now take any name from the user, find whether that name is present in that array or not, and print the position of that name in the array if found. Write a search method to sequentially search the name from the array. Invoke the search method from the main method. The array and the name to be searched should be passed into the search method as parameters.Now write a Java program to implement binary search for the above problem.[Hint: You can use equals() and compareTo() methods of String class.]cipher and the player tries to decrypt it by using common letter combinations in English and deduction. The game should have an array with 6 or more different Strings each containing a paragraph of text. Since a whole paragraph can’t normally fit on one line, paragraphs should be split into multiple lines using \n. You can try to place \n in such a way that they help figure out the message. When the game starts it should display a menu with two options: normal mode or test mode. In normal mode one of the quotes should be picked randomly. In test mode the user should be shown one more menu that displays truncated versions of the strings and let the user choose one. Truncated paragraphs should contain the maximum number of words that can fit within a 50-character limit or only the first line of the paragraph, whichever is shorter. This should be accomplished programmatically.Create Java Program that ask the user to insert array length and then ask the user to insert array elements, the program should include a method which calculate the average of the array elements and return a double value. marking mode considering mostly how dynamic is the code performs.
