*in java* Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print:90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline.   import java.util.Scanner; public class PrintWithComma { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); final int NUM_VALS = 4; int[] hourlyTemp = new int[NUM_VALS]; int i; for (i = 0; i < hourlyTemp.length; ++i) { hourlyTemp[i] = scnr.nextInt(); } /* Your solution goes here */ System.out.println(""); } }

Java Complete the method with explaining, thank you!

Write a Java program to implement the following: Ask the user to enter the names of 3 Books and store them in an ArrayList called Book  Remove the second book from the list  Add the user to enter a new book name and store to be the first book of the list  Ask the user to enter a book name, search for it in list, and print “exist” or “not exist”  Print the book name at index 2  Print all list items using loop  Print the size of the list

JAVA Chapter 9 Multidimensional Arrays and the ArrayList Class Write a value returning method that returns the sum of the elements in the last column of each row in a two-dimensional array of ints. Include code to test your method.

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…

Write a call to Arrays static method equals with arguments arrayl and array2.

import java.util.Arrays; import java.util.Random;   public class Board {   /** * Construct a puzzle board by beginning with a solved board and then * making a number of random moves.  That some of the possible moves * don't actually change what the board looks like. *  * @param moves the number of moves to make when generating the board. */ public Board(int moves) { throw new RuntimeException("Not implemented"); } The board is 5 X 5. You can add classes and imports like rand.

Method Details: public static java.lang.String getArrayString​(int[] array, char separator) Return a string where each array entry (except the last one) is followed by the specified separator. An empty string will be return if the array has no elements. Parameters: array - separator - Returns: stringThrows:java.lang.IllegalArgumentException - When a null array parameter is provided

Integers numberOfParts, required Groups, and invalid Groups are read from input. If numberOfParts is 21 or more, then add 3 to requiredGroups. Otherwise, add 6 to invalidGroups. ► Click here for examples 3 public class GroupSurvey { 4 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int numberOfParts; int requiredGroups; I int invalidGroups; 345679 8 9 10 11 12 13 14 15 16 17 18 19 20 } numberOfParts = scnr.nextInt (); requiredGroups = scnr.nextInt (); invalidGroups = scnr.nextInt (); /* Your code goes here */ if(numberOfParts>21){ requiredGroups= System.out.println(requiredGroups); System.out.println(invalidGroups);

Use the ArrayList class Add and remove objects from an ArrayList Protect from index errors when removing Practice with input loop Details: This homework is for you to get practice adding and removing objects from an ArrayList. 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…
