问题 I am stuck on my tictactoe problem. Define a calss called TicTacToe. An object of type TicTacToe is a single game of TicTacToe. Store the game board as a single 2d array of base type char that has three rows and three columns. Include methods to add a move, display the board, to tell whose turn it is, to tell whether there is a winnner, to say who the winner is, and to restart the game to the beginning. Write a main method for the class that will allow two players to enter their moves in turn

问题 This program asks the user to input a number and then brings back the details from an list. how do I do this? do { Scanner in = new Scanner(System.in); System.out.println("Enter Number <terminated by 1>"); } while (!input.equals("-1")); System.out.println("Session Over"); } catch (Exception e) { System.out.println(e); } } } output: Enter Number <terminated by 1> 123456 Person Number: 12 回答1: while (input != -1); would be the right way to compare two integer values. 回答2: In java you can't test

问题 I haven't coded in a few years and have been writing simple Java programs to re-familiarize myself with basic principles. However, I'm having trouble getting my do-while loop to act how I want it to. I guess I'm not understanding exactly how do-while loops work, but what I want is to gather user input from System.in as an int, and continue to ask for a valid int input if they enter some other data form. What I have is: do { System.out.print("Input: "); userOption = userInput.nextInt(); }

问题 I am working on media management script for my environment in which I want that I should pick values from file or array for different pool and libraries, run the commands based on those inputs and mail the output based on those commands to a different people. like, run command based on First pool, first library and then mail to the first person in file/array. or it will be great if it can match the things and need not to depend on serial order. code is : pool=(apple Mango Banana) library=

问题 I'm trying to print something in a document, but it only works for the first value of h that I tried!

问题 I have a classic ASP page with a simple html table, and I want to loop the table rows based on a unknown number of records pulled from the database, however, when I am looping the records with a do/while loop, I am getting an error saying that Either BOF or EOF is True. I want every other row of the table to alternate background colors (the colors I have set in CSS). <% do while not rsTest.eof %> <tr class="odd"> <td colspan="5"><%=(rsTest.Fields.Item("field").Value)%></td> </tr> <% rsTest
