[英]Code after while loop not accepting input [Java]
So, in this program when the while loop ends, it properly displays "You Win!" 因此,在该程序中,当while循环结束时,它将正确显示“ You Win!”。 and it does execute the code asking if the user wants to view credits. 并且会执行代码,询问用户是否要查看积分。 However, the input isn't being accepted after the question and the program ends without accepting any input. 但是,问题之后将不接受输入,并且程序将不接受任何输入而结束。
Scanner scan = new Scanner(System.in);
System.out.println("Would you like to play a game called Threes? Y/N");
String answer = scan.nextLine(); //Simple yes or no
if (answer.contains("Y") || (answer.contains("y"))) {
System.out.println("OK, want to know how it works? Y/N");
String answer2 = scan.nextLine();
if (answer2.contains("n") || (answer2.contains("N"))) {
System.out.println("OK, Enter a single number.");
int mistake = 0; //Used as a counter for number of division mistakes made
int numstart = scan.nextInt(); //First number input
int current = numstart; //Current number displayed - starts as the first number
System.out.println("Enter 1 or -1 if you're adding or subtracting, and 0 to divide.");
System.out.println(numstart); //Displays first number input
int input = scan.nextInt(); //First function performed by user
while (current != 1) { //The game will run until the number '1' is reached
if (input == 1) { //If '1' is input, add one to the number, and display new number
current++;
System.out.println(current);
input = scan.nextInt();
}
if (input == -1) { //If '-1' is input, subtract one from the number, and display new number
current--;
System.out.println(current);
input = scan.nextInt();
}
if (input == 0) { //If '0' is input, try to divide
if (current % 3 != 0 && current != 1) { //If you can't divide by three, try again
System.out.println("Try again.");
mistake++;
input = scan.nextInt();
}
if (current % 3 == 0) { //If you can divide, do it and display new number
current = current / 3;
System.out.println(current);
input = scan.nextInt();
}
}
if (input == 69 || input == 666) //Cheat code! If you input 69 or 666, you automatically win
break;
if (((input > 1) && (input != 69) && (input != 666)) || input < -1) { //If input is not valid, try again and display error
System.out.println("Error - wrong input.");
input = scan.nextInt();
}
}
System.out.println("You Win! Mistakes: " + mistake + "\n"); //Will display a win condition, and amount of division errors
System.out.println("Thank you for playing Threes \n - Chris Burbach");
}
System.out.println("Credits? Y/N");
String credits = scan.nextLine();
if(credits.contains("Y")||credits.contains("y"))
{
System.out.println("\n***********************************************************************");
System.out.println("*Threes: a game of dividing by three - inspired by my boredom in class*");
System.out.println("***********************************************************************");
Sorry for any confusion, I figured it out. 很抱歉给您带来任何混乱,我知道了。 After each instance of "You Win!", outside of its nested if statement, I needed to add scan.nextLine();
在“ You Win!”的每个实例之后,在其嵌套的if语句之外,我需要添加scan.nextLine();
because of it returning a newline character and terminating the program due to an empty input. 因为它返回换行符并由于输入为空而终止程序。
