How to keep the loop repeating if the user keeps entering a negative number in Java ?

System.out.println("PLease enter number of cake :"); cakeNo = scan.nextInt(); if (cakeNo < 0) { System.out.println("Please enter a positive number of cake :"); // outputs this if the user enters a negative number cakeNo = scan.nextInt(); } else { cakeTime = cakeTime * cakeNo; }

If you want a loop, you'll have to use a while instead of an if, and remove the else.

if-else statements are conditional statements which offer selection, not loops. They are not capable of looping your program.
