variables

问题 I have a very simple question, or at least I think it is simple. Currently I'm trying to use the robot class with variables. What I mean by this is the following (the variables "pass" are chars.) pass1 = 0; pass2 = 0; pass3 = 0; pass4 = 0; try{ Robot robot = new Robot(); robot.delay(2000); robot.mouseMove(1318, 322); robot.keyPress(pass1); robot.keyPress(pass2); robot.keyPress(pass3); robot.keyPress(pass4); } catch (AWTException e) {e.printStackTrace();} When I run the program, I get this

问题 Say I am making something like a quiz, and I have a counter to show the number of questions that have been answered correctly. When one question is correctly answered, and a new screen(Activity) is shown, how do I carry over the number to the next screen? 回答1: When you say screens do you mean Activities? Then you probably want to pass them via extras in your intents. Activity 1: int score; ... Intent Intent = new Intent(...); intent.putExtra("score_key", score); startActivity(intent);

问题 I used this program to take input mm as the month of the year and print out the name of the month: #include <stdio.h> #include <string.h> int main(){ int mm; printf("input month "); scanf("%d", &mm); char mname[9]; if (mm == 1) {mname = "January";} if (mm == 2) {mname = "February";} if (mm == 3) {mname = "March";} if (mm == 4) {mname = "April";} if (mm == 5) {mname = "May";} if (mm == 6) {mname = "June";} if (mm == 7) {mname = "July";} if (mm == 8) {mname = "August";} if (mm == 9) {mname =

问题 How do I restart my score when I reload a screen public class KeepingScore: Monobehaviour; public static int Score; I also have score set as whenever I click on an object, the object is destroyed and gives me a point. void OnMouseDown() KeepingScore.score += 1; Destroy(); I also have a timer where when I run out of time, scene switches to level select menu, where I click on the level again (ie level 1), but then I still see my score back how it was. I know it's static therefore It's still the

问题 I am trying to get the Play! framework up and running. After I extracted Play! version 2.3.0 to C:\Play and adding that directory ( C:\Play ) to my path in 'Environment Variables' (separated form the other paths with a ;), I tried running it with the command "Play new foobar" and I keep getting the error "'Play' is not recognized as an internal or external command, operable program or batch file." I have looked at a few possible fixes to this on here Configuration Variables in Play! Framework

问题 I'm trying to create a HTML file input field which can add files (in this case images) multiple times, instead of replacing existing chosen files. The file field will always replace the previous selection. What I am trying to do is store the selection somewhere else each time user selects a file. $("#imageInput").change(function() { if(typeof window.images == "undefined"){ window.images = this.files; } else { var k = 0; console.log(window.images.length); //always equals to this.files.length

问题 I need some assistance, please. I'm trying to create a batch file to move files from one folder to another. The file name will have variable yyyy-mm format plus additional data before or after the date. The batch will need to move the file to a server directory with the same mmmm-yy folder name. I've come up with the code below, but it doesn't quite work. A "Missing Operand" error is returned. The new directory is created but the files are not moving from the old folder to the new one. My

问题 I'm writing a script that needs to take advantage of a Java daemon via the local dbus of the linux machines it will run on. This daemon in particular will return an array of tuples which I want so that I can parse through/use the information in later in my code. I want this code to take this value from multiple machines at once, but the problem is the only way I see to really take return/exit values from a terminal which I am ssh'ed into is by parsing stdout's output. I don't want to do this,
