Here is a while loop, write the equivalent do-while loop. Scanner scan = new Scanner(System.in); int sum = 0; int num = scan.nextInt();   while(num != 0) { sum += num; num = scan.nextInt(); } System.out.println(sum);

Simple try-catch Program This lab is a simple program that demonstrates how try-catch works. You will notice the output when you enter incorrect input (for example, enter a string or double instead of an integer). Type up the code, execute and submit the results ONLY. Do at least 2 valid inputs and 1 invalid. NOTE: The program does not stop executing after it encounters an error! CODE: import java.util.Scanner; public class TryCatch Example Simple { public static void main(String[] args) { Scanner input = new Scanner(System.in); int num = 0; System.out.println("Even number tester.\n"); System.out.println("Enter your name: "); String name = input.nextLine(); while (true) { try { System.out.println("Enter an integer : ");

using System; class TicTacToe { Console.WriteLine("Do you want be X or O: "); Console.Write("Press 1 for 'X' or Press 2 for 'O'\n"); choice = int.Parse(Console.ReadLine()); if(choice==1) staticint player = 1 staticint choice; { staticvoid Print(char[] board) { Console.WriteLine(); Console.WriteLine($" {board[0]} | {board[1]} | {board[2]} "); Console.WriteLine($" {board[3]} | {board[4]} | {board[5]} "); Console.WriteLine($" {board[6]} | {board[7]} | {board[8]} "); Console.WriteLine(); } staticvoid Main(string[] args) { char[] board = newchar[9]; for (int i = 0; i < 9; i = i + 1) { board[i] = ' '; } Print(board); board[4] = 'X'; Print(board); board[0] = 'O'; Print(board); board[3] = 'X'; Print(board); board[5] = 'O'; Print(board); board[6] = 'X'; Print(board); board[2] = 'O'; Print(board); } } }   How can this program be fixed to ask the user "It is your turn to place an X. Where would you like to place it?"

Explain what the code does step by step.

JAVA Language:  Transpose Rotate.  Question:  Modify Transpose.encode() so that it uses a rotation instead of a reversal. That is, a word like “hello” should be encoded as “ohell” with a rotation of one character. (Hint: use a loop to append the letters into a new string)         import java.util.*;            public class TestTranspose {        public static void main(String[] args) {          String plain = "this is the secret message";   // Here's the message           Transpose transpose = new Transpose();          String secret = transpose.encrypt(plain);          System.out.println("\n ********* Transpose Cipher Encryption *********");          System.out.println("PlainText: " + plain);    // Display the results          System.out.println("Encrypted: " + secret);          System.out.println("Decrypted: " + transpose.decrypt(secret));// Decrypt        }      }            abstract class Cipher {        public String encrypt(String s) {          StringBuffer result = new…
