do-while

问题 I have created my menu with do~while(true); but every time the user insert a number, instead of running the program it shows the the menu again! what do you think? // my main method public static void main(String[] args) { DataReader reader = new DataReader(); // The reader is used to read data from a file // Load data from the file if(reader.loadData(args[0])) { // The filename is entered using a command-line argument vehicles= reader.getVehicleData(); // Store the arrays of Vehicle //

问题 Wondering if it's possible to finagle this logic (checking a variable for changes over time and running a loop while true) into a bash if statement or while loop condition. I was hoping for something like: var=$(du -h *flat*.vmdk) var2=$(sleep 1 ; du -h *flat*.vmdk) if [[ $var != $var2 ]]; then while true do echo -ne $(du -h *flat*.vmdk)\\r sleep 1 done else echo "Transfer complete" fi I've also played with a while loop , rather than an if then with no luck. while [ $var != $var2 ] ; do echo

问题 I've this basic Arduino code, and I want to have 2 options to exit this Do-While loop . I simplified my original code to highlight the real problem: the Do-While doesn't recognize the OR || condition to exit the loop In this code I'm starting with two integer variables that are equal to zero and as soon as they enter the Do-While, they'will be setted equal to 2 both, so that they can immediately exit the Do-While in the first iteration. Here's my code: int fin = 0; int ending = 0; int counter

问题 This question already has answers here : Non duplicates numbers in user input (5 answers) Closed last month . With this Lottery program I am trying to make sure the number are within a range of 1-59, The same number cannot be entered twice and that only numbers can be entered. The only bit of code I need help on is on the only numbers can be entered part. public void choose() { System.out.println("\n"); int temp; boolean valid; for (int i = 0; i < 6; i++) { do { valid = true; System.out.print
