Chapter 5.6, Problem 5.6.2CP

What are the differences between a while loop and a do-while loop? Convert the following while loop into a do-while loop:

Scanner input= new Scanner(System.in);

int sum = 0;

System.out.println("Enter an integer " +

"(the input ends if it is 0)");

int number = input.nextInt();

while (number != 0) {

sum += number;

System.out.println("Enter an integer " +

"(the input ends if it is 0)");

number = input.nextlnt();

}
