using System;class Program{  public static void Main(string[] args)   {  int number = 1;  while (number <= 1000)    {      Console.WriteLine(number);    number = number + 1;    }  }} this program counts from 1-1000 in C#. how would it be changed to use the += operator to add one to number, instead of writing number = number + 1?

Java true or false: The method public boolean simpleMethod() { return true; } is a valid mutator?

Consider the following piece of code. (The numbers on the left margin denote line numbers.) line#01 public class funcRef {02     private int n;03     public funcRef (int m) {n = m;}04     public static void func (funcRef t) {t.n++;}05     public static void main (String [] args) {06         funcRef t1, t2;07         t1 = new funcRef(20);08         t2 = t1;09         System.out.print(t2.n);10         func(t1);11         System.out.print(t2.n);12         func(t1);13         System.out.print(t1.n);14         func(t2);15         System.out.print(t1.n);16         func(t2);17         System.out.print(t1.n);18         System.out.print(t1.n);19         return;20     }21 } Out of the following, tick the true statements and leave the false statements unticked.(More than one of the statements could be true. You get full marks only for marking all the statements correctly. There are no partial marks.) A. The output of the program will be 202022222222. B. When func(t1) is called in line…

Please answer 6 and 7 as they are associated altogether. 6. The FixProgram.java below has some errors.a. Fix the errors so that the program successfully compiles and runs. class FixProgram{ public static void main(String[] args) { System.out.println('Hello World!') }}  7. Change the SampleProgram.java program below.a. So that it displays Programming is fun! Instead of Hello World! class SampleProgram{ public static void main(String[] args) { System.out.println("Hello World!"); }}
