问题 This question already has answers here : How to handle infinite loop caused by invalid input (InputMismatchException) using Scanner (5 answers) Closed 2 years ago . In my program I'm trying to get a user to input an int between 1-3 and then do something based off what they type. If it is not a number or not one of the options then it will allow them to reenter a valid option. The issue I have is I'm having trouble brainstorming how to not have it infinitely loop and just allow them to enter

问题 I was trying some code at JSBin and got weird results. This should work - it's a simple loop that uses Window.prompt. It does execute the correct number of times using Stack Snippets: for (let i = 0; i < 3; i++) { console.log(`i: ${i}`); let foo = prompt('Enter anyting - it will be echoed.'); console.log(`echo: ${foo}`); } Yet on JSBin it only runs for one iteration. If you open the browser console, there is an warning message: Exiting potential infinite loop at line 1. To disable loop

Wikipedia page parsing program caught in endless graph cycle

问题 My program is caught in a cycle that never ends, and I can't see how it get into this trap, or how to avoid it. It's parsing Wikipedia data and I think it's just following a connected component around and around. Maybe I can store the pages I've visited already in a set and if a page is in that set I won't go back to it? This is my project, its quite small, only three short classes. This is a link to the data it generates, I stopped it short, otherwise it would have gone on and on. This is

问题 exports.addNewValue = functions.database.ref('/path') .onWrite(event => { event.data.adminRef.update({"timeSnapshot":Date.now()})}) It appears that Date.now() causes an infinite loop in the function because the following does not: exports.addNewValue = functions.database.ref('/path') .onWrite(event => { event.data.adminRef.update({"timeSnapshot":"newString"})}) How do I fix this? 回答1: If you write back to the same location in the database that was previously changed, you can expect this

How to stop infinite loop in JShell / Kulla?

问题 JShell is a Java REPL that is scheduled to be released alongside Java 9; however, there is an open beta for it. If I create an infinite loop in JShell (Project Kulla) by typing: -> while(true) {} JShell will loop forever. Short of completely quitting JShell, is there a way to stop an individual line of code while it's running in JShell (after you have already begun evaluation of the code)? 回答1: Actually there is a way. Just hit CTRL + c : -> while(true) {} Killed. -> It'll kill the loop and

问题 I am stuck in a situation where I need to generate a defined frequency of some Hz. I have tried multimedia timers and all other stuff available on the internet but so far an infinite loop with some if-else conditions gave me the best results. But the problem in this approach is that it consumes almost all of the cpu leaving no space for other applications to work properly. I need an algorithm with either generates frequency of some Hz to KHz. I am using windows plateform with C#. 回答1: You can
