Do while loop practice Java

Hello again... next code I stuck and can’t find out what’s wrong is import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int number = scanner.nextInt(); //take input and output corresponding message /* 1 => Language selection 2 => Customer support 3 => Check the balance 4 => Check loan balance 0 => Exit */ do { if(number==1){ System.out.println("Language selection"); } else if (number==2){ System.out.println("Customer support"); } else if (number==3){ System.out.println("Check the balance"); } else if (number==4){ System.out.println("Check loan balance"); } } while (number != 0); System.out.println("Exit"); } } When I run the tests I get >> Execution timed out ! Thank you for your help

well, firstly i would add a way to get input in the do part of the loop so it won’t just take the same number over and over. that would fix the problem because you could make the number 0 and end the program before it goes over the time limit on sololearn. also move the print exit outside of the loop because otherwise it will print every time the loop runs

hey zer0x0 that is because the while loop is executing infinitely because the condition is never false and that causes the time out error

zer0x0 Instead of using if else inside do while loop you can use switch because it will break the loop when condition will satisfy. int number = 0; do { number = scanner.nextInt(); switch (number) { case 1: //Statement break; case 2: //Statement break; case 3: //Statement break; case 4: //Statement break; case 0: //Statement break; } } while (number > 0);

HI all , is there a problem with the proposed solution for the Do..while loop in the java course ? it seems working but it wont compile on the simulator . how can i complete the course ? import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner read = new Scanner(System.in); int password ; do { System.out.println("write password"); password = read.nextInt(); } while (password != 8819); } }
