1. Revise the following code so that it uses a while loop instead of a dowhile

loop:

Scanner keyboard = new Scanner(System.in);

int number;

{

System.out.println("Enter a whole number:");

number = keyboard.nextInt();

System.out.println("You entered " + number);

} while (number > 0);

System.out.println("number after loop = " + number);

2. What output is produced by the following code?

{

System.out.println(count);

count;

}

System.out.println("count after loop = " + count);
