Scanner in Java not working

由 冷暖自知 提交于 2021-02-04 13:44:04
问题 I'm trying to write a very simple number guessing game (code is below). After 1 round is finished, the user is supposed to be able to decide whether he/she wants to play another round or not. Problem is, the program always skips the last question (never letting the user answer 'y' or otherwise. What am I missing here? Is there something about java.util.Scanner I don't know about? import java.util.Random; import java.util.Scanner; public class GuessNum { public GuessNum() { int numRandom = 0;

问题 Actually, I can easily found a similar question in Google, but it still can not solve my question. How to prevent non-numeric input in C? The upper-link is like a similar case.

Is there a way to set the data type of 'object' to the data type of the user's input value? IOW, such that if object=1, type(object)=int? I know I can set the data type of an input to int using the following: object = int(input("Please enter an integer")) In this case, if

问题 I'm doing a counter where I'm showing how many seconds the user has to make the input. The problem is that when I use scanf(), the program will stop and will wait for the answer, but I don't want that. I'd like to keep running the counter even thought the user doesn't put anything. Example: for(int i=10;i>=0;i--){ i==0? printf("time over\n"):printf("%d seconds left\n",i); scanf("%s", decision); sleep(1); } What can i do to solve this? 回答1: Like mentioned in the comments one possibility would
