I’m working on implementing a server in Java to handle a multiplayer Minesweeper game. In trying to test my server to ensure that it responds correctly to legal client requests, I am finding that the tests only pass if I add a System.out.println(in.readLine()) statement after printing a particular client request to the output stream but… Read More Why do my Java server tests pass when I add a System.out.println(in.readLine()) statement before the tests, but fail without that statement?

I’m working on a small shell and using libreadline to get command input. problem My command prompt is getting deleted when I use C-W note this only happens after I enter a word and then C-W, C-w immediately doesn’t delete the prompt. source #include <stdio.h> #include <readline/readline.h> #include <readline/history.h> #include <stdlib.h> #include <string.h> int ash_loop(void)… Read More C-W is deleting my command prompt – how to stop this

I am learning Kotlin using codeacademy. In the Madlibs project I was asked to read an number input using readLine() from the user and then convert it to an integer. I want to know which of the two solutions is better moving forward. This was my solution: distance = readLine()!!.toInt() This was the given solution:… Read More Which is better? Integer.valueOf(readLine()) or readLine()!!.toInt()

I need to write a function to validate the time of user input from console. The format of the time is HH:mm in 24 hours time. function isValidTime(timeString) { var regex_time = /^\d{2}\:\d{2}$/; if(!regex_time.test(timeString)) { return false; } var hour = timeString.getHour(); var minute = timeString.getMinutes(); if ((hour > 0 && hour <= 23) &&… Read More Validate Time of user input

I’m writing code in Intelij. readLine does not correctly read the input (puts a line break at the end of the line), which is why the next readline does not work (becomes automatically empty). Code: public class Start { public static void main(String[] args) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String s… Read More ReadLine (Buffered reader) does not work in a loop
