The infinite loops, sometimes, result intoStackOverflowErrororOutOfMemoryErrorbased on what we are trying to do in the loop. If there are no memory leaks, it is possible that the loop never terminates and executes infinitely. The program will hang in this situation. 4. Difference betweenWhile-...

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) { Scann...
