Declare an array of String type and size 3. Initialize it with 3 names of your good friends. Print out the names using a for-each loop, not a regular for loop.

What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?

mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.

Using jGRASP please de-bug this /**This program demonstrates an array of String objects.It should print out the days and the number of hours spent at work each day.It should print out the day of the week with the most hours workedIt should print out the average number of hours worked each dayThis is what should display when the program runs as it shouldSunday has 12 hours worked.Monday has 9 hours worked.Tuesday has 8 hours worked.Wednesday has 13 hours worked.Thursday has 6 hours worked.Friday has 4 hours worked.Saturday has 0 hours worked.Highest Day is Wednesday with 13 hours workedAverage hours worked in the week is 7.43 hours*/{public class WorkDays{public static void main(String[] args){String[] days = { "Sunday", "Monday", "Tuesday","Wednesday", "Thursday", "Friday", "Saturday"}; int[] hours = { 12, 9, 8, 13, 6, 4}; int average = 0.0;int highest = 0;String highestDay = " ";int sum = 0; for (int index = 0; index < days.length; index++){System.out.println(days[index] + " has "…

a. Create a 1D array of integers to store 50 integers. b. Store values from 0 to 49 into the array you just created. c. Create a new String Object using no-arg constructor. d. Using for loop append the array elements one by one to the String (one per loop iteration) e. Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)). E.g. "It took nanoseconds to append 50 integers to the String

Try using the ref or out keyword to pass in an array argument and see what happens.

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.             The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std;   // Global constants const int ROWS = 3;  // The number of rows in the array const int COLS = 3;  // The number of columns in the array const int MIN = 1;  // The value of the smallest number const int MAX = 9;  // The value of the largest number //…
