- If the following array declarations are valid, write "VALID". Otherwise, make assumptions and write a correct declaration. int[50] list; 1. int size; double[] list=new double[size]; 2. int[] test=new int[-5]; 3. double[] sales=new double[25.5]; 4. int x,y; char[x][y] board=new board[][] 5.5.24 LAB: Shift right (JAVA) Write a program in java that reads a list of integers from input into an array and modifies the array by shifting each element to the right one position and by shifting the last element to the first position. The input begins with an integer indicating the number of values that follow. Output the modified array and end with a newline. Ex: If the input is: 6 2 4 6 8 10 12 the output is: 12 2 4 6 8 10 For coding simplicity, follow every output value by a space, including the last one. Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}Determine whether the following array declarations are valid. If a declaration is invalid, explain why. a. int list[61];b. strings names[20];c. double gpa[];d. double[-50] ratings[];e. string flowers[35];f. int SIZE = 10;double sales[2 * SIZE];g. int MAX_SIZE = 50;double sales[100 - 2 * MAX_SIZE];
- using java programming int a[] = {5,10,4,20,1,7}; 1- search for the smallest element in array 2-if you found the smallest element in the array :swap the first element with the smallest elementDetermine whether the following array declarations are valid. If a declaration is valid, determine the size of the array. a. int list[] = {18, 13, 14, 16};b. int x[10] = {1, 7, 5, 3, 2, 8};c. double y[4] = {2.0, 5.0, 8.0, 11.0, 14.0};d. double lengths[] = {8.2, 3.9, 6.4, 5.7, 7.3};e. int list[7] = {12, 13, , 14, 16, , 8};f. string name[8] = {"John", "Lisa", "Chris", "Katie"};2.3 Write a program that allows you to create an integer array of 18 elements with the following values: int A[] = {3, 2, 4, 5, 6, 4, 5, 7, 3, 2, 3, 4, 7, 1, 2, 0, 0, 0}. Perform the following computations, a.Compute the sum of elements from index 0 to 14 and stores it at element 15 b.Compute the average of all numbers and stores it at element 16 c.Identifies the smallest value from the array and stores it at element 17 6.2 Create a Product class with Product Id & Product Name.

- 9.1.1: Output numbers in reverse. Write a program that reads a list of 10 integers, and outputs those integers in reverse. For coding simplicity, follow each output integer by a space, including the last one. Then, output a newline. Ex: If the input is 2 4 6 8 10 12 14 16 18 20, the output is: 20 18 16 14 12 10 8 6 4 2 To achieve the above, first, read the integers into an array. Then output the array in reverse. CODES in Coral Languagevoid mystery2(int list[], int length) { for (int i = 0; i < length - 1; i++) { if (i % 2 == 0) { list[i]++; } else { list[i]--; } }} For each array below, indicate what the array's contents would be after the function were called and passed that array as its parameter. use the following as input. {6, 3} {2, 4, 6} {1, 2, 3, 4} {2, 2, 2, 2, 2} {7, 3, 2, 0, 5, 1}Nrite a program in Java that reads 10 integers and store them in AN ArrayList. Then, do the following: ) Print the ArrayList in the reverse order b) Sort the ArrayList, and display the data after sorting c) Print the largest and the smallest element in the ArrayList
- Java Program. Write a function that returns the index of the smallest element in an array of doubles. If there are more such elements than one, return the last index is fine. Using the following header: int IndexOfSmallestArray(double array[], int size) Finish the function implement only.Define the meaning of the following array by illustrating the array list. i. int total[10] = {0}; ii. int total[10] = {8, 5, 12}; iii. int total[ ] = {5, 6, 3}; iv. total[2] = 3; v. int total[4] = {1, 2, 3, 4};5.29 LAB: Is array sorted (JAVA) Write a program in java that reads a list of integers from input into an array and outputs "yes" if the list is sorted in ascending order between two provided positions. Otherwise, output "no". The first input specifies the number of items in the list. The next set of inputs is the list. The last two inputs are the start and end positions (inclusive). Assume the list contains less than 20 integers and position 1 is the first element. Ex: If the input is: 8 5 6 7 4 3 2 1 0 1 3 the output is: yes Ex: If the input is: 6 1 2 3 4 5 2 4 6 the output is: no Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}
