int [] numbers = new int[5];
int [] sums;
A: numbers references an array of 5 elements and sums references nothing (null)
B: numbers and sums reference integers
C: numbers references an array of 5 elements and sums references several integers
Which one?
: numbers references an array of 5 elements and sums references nothing (null)
No memory is allocated to sums array. Numbers array references array of 5 elements of type integers

A method called linearSearch(), which takes as parameters an array of int followed by three values of type int, and returns a value of type int. The first int parameter represents a key, the second int parameter represents a starting position, and the third int parameter represents an end position. If the key occurs in the array between the start position (inclusive) and the end position (exclusive), the method returns the position of the first occurrence of the key in...
Can someone finish this class for me? There are comment instructions with what to do in the methods already. public class ArrayDemo { public void demonstrateTask1(){ System.out.println("Demonstrate Task 1"); int[] numbers = null; // note that numbers references nothing (null) initially ...
JAVA 1.Write a static method named getMaxEven(numbers) which takes an array of positive integers as a parameter. This method calculates and returns the largest even number in the list. If there are no even numbers in the array, the method should return 0. You can assume that the array is not empty. For example: Test Result int[] values = {1, 4, 5, 9}; System.out.println(getMaxEven(values)); 4 System.out.println(getMaxEven(new int[]{1, 3, 5, 9})); 0 public static int --------------------------------------------------------------------------------- 2. Write a static method...
(JAVA) Given an array of unique positive integers, write a function findSums that takes the array input and: 1. Creates a hashtable called “hashT” and inserts all the elements of the input array in the hashtable. 2. Finds pairs of elements in the hashtable whose sum is another element (sum) in the hashtable and print the pairs in the console. 3. Returns another hashtable names “sums” of those sum elements. For example: Input: [1,5,4,6,7,9] Output: [6,5,7,9] Explanation: 6 = 1...

Write a program in C that creates an array of 100 random numbers from 0-99. The program sums the random numbers and prints the sum. It then writes the numbers to a new file using open, close and write. Then looks in the current directory for files that match the pattern “numbers.XXXX”. For each file, open the file and read the file. You can assume that the file will contain 100 integers. Sum the integers. Print the filename and the sum...
Which of the following are valid array declarations? a. int[] array- new int[10]; b. double [array double[10]; c. charl charArray "Computer Science"; None of the above Analyze the following code: class Test public static void main(Stringl] args) System.out.println(xMethod(10); public static int xMethod(int n) System.out.println("int"); return n; public static long xMethod(long n) System.out.,println("long"); return n The program displays int followed by 10 The program displays long followed by 10. The program does not compile. None of the above. tions 3-4 are...
What elements does the array numbers contain after the following code is executec int[] numbers = new int [8]; numbers [1] = 3; numbers [4] = 99; numbers [7] = 2; int x = numbers[1]; numbers(x) = 44; numbers (numbers [7]] = 11; O 13, 11, 44, 99, 2] O 10, 3, 11, 44, 99, 0, 0, 2] O 13, 0, 11, 44, 99, 0, 21 O 10, 3, 2, 44, 99, 0, 0, 11]
(C++ program )Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to the element 1 of the new array. Element 1 of the argument array should be copied to element 2 of the new array, and so forth....
Programming language C Please go through this carefully. Needs function void add(int *a1, int n, int *a2) Write a program addition.c that reads in an array (a1) of numbers, and creates a new array (a2) of numbers such that the first and last numbers of a1 are added and stored as the first number, the second and second-to-last numbers are added and stored as the second number, and so on. You need to check for even and odd length of...
