[英]Guessing game loop
这是我制作的猜谜游戏的代码。 我的计数器没有增加超过 1。我正在从一个单独的控制器类传递参数选择和生成的数字。 do while 循环应该在控制器类中吗?
public String startGuessingGame(int choice, int generatedNumber) {
int count = 0;
final int attempts = 4;
String result = null;
do {
count++;
if (choice == generatedNumber) {
result = "Attempt " + count + " "
+ "- You have guessed the correct number!";
}
else if (choice > 50 || choice < 0) {
result = "Out of range. "
+ "\nPlease choose a number between 1 and 50.";
}
else if (choice > generatedNumber) {
result = "Attempt " + count + " "
+ " - You have guessed too high!";
}
else if (choice < generatedNumber) {
result = "Attempt " + count + " "
+ "- You have guessed too low!";
}
if (count == attempts) {
result = "You are out of guesses! The number was " + generatedNumber;
}
}
while(count < attempts);
return result;
}
}
这里没有循环。 您正在寻找类似while(count < attempts)
。
您需要将count
设置为控制器类的类变量(成员),并在该类中设置 do/while 循环,以便startGuessingGame
仅处理用户选择的验证。 像这样,但代码远未完成
public class SomeControllerClass() {
final int attempts = 4;
int count = 0;
public void someMethod() {
int choice = 0;
do {
choice = getChoice();
count++;
String text = otherClass.startGuessingGame(choice, generatedNumber);
while (count < attempts);
}
并且该方法仅进行验证
public String startGuessingGame(int choice, int generatedNumber) {
String result = null;
if (choice == generatedNumber) {
result = "Attempt " + count + " "
+ "- You have guessed the correct number!";
} else if (choice > 50 || choice < 0) {
//and so on
return result;
}
试试这个:在while
条件之前增加计数器:
do{
...
if (count == attempts) {
result = "You are out of guesses! The number was " + generatedNumber;
}
count++;
}while(count < attempts);
return result;
...
