Answer 1

Sorry, I don't speak your language. However, the code you have posted is not Java and that's the language you've tagged.
Are you trying to use C# code in Java?

Answer 2

static void Main(string[] arg) { //🧐

Answer 3

На С# это неплохо. На Java будет как ниже:

using System;
using System.IO;
using System.Collections.Generic;
using System.Net.NetworkInformation;
using System.Threading;
using System.Text.RegularExpressions;

public class TestLambdaExpression
{
public static void Main()
{
List<string> tests = new List<string>() { "#FFFFFF", "#12ABCD", "#FF3421", "#00ff00", "232323", "f#fddee", "#fd2", "FFFFFF", "AAAAAAA", "#ABCDEFGH", "#QQQQQQ", "#######" };
tests.ForEach(e => Valid(e));
Console.ReadLine();
}

static void Valid(string str)
{
Regex rx = new Regex("^#[0-9A-F][0-9A-F][0-9A-F][0-9A-F][0-9A-F][0-9A-F]");
if (str.Length == 7 && rx.IsMatch(str.ToUpper()))
Console.WriteLine(str + " is Valid");
else
Console.WriteLine(str + " is NOT Valid");
}

Answer 16

Problem
Using methods, create a program that will, on a given set of scores keyed-in by the user, will compute for the measures of central tendency. Use an array to contain maximum of 25 scores. Create the following method: GetMean, GetMedian. You may refer to the following, how to obtain the result:
Mean - returns the average value of the scores
Median - returns the mid-point value of given scores after sorting
Approach: To solve the problem, follow the below steps:
To find Mean:
At first, find the sum of all the numbers present in the array. Then, simply divide the resulted sum by the size of the array

To find median:
First, simply sort the array
Then, check if the number of elements present in the array is even or odd
If odd, then simply return the mid value of the array
Else, the median is the average of the two middle values
