Question
complete the dry run , state what is printed by the code and justify with step by step explanation of the execution of the code
![(iii) Scanner scanner - new Scanner (System.in);
boolean done - false;
int num= -1;
while (!done) (
}
System.out.print("Enter a number: ");
String read - scanner.nextLine();
// isInteger returns true/false accordingly
if (isInteger (read)) {
}
num - Integer.parseInt (read);
done true;
// 12
// 13
// 14
// 15
// L6
// 17
// 18
// 19
System.out.println("Read: " + num);
// L10
Reminder: Integer.parseInt converts a numerical string to an int.
For this question, assume:
• is Integer is a method that returns true if the argument corresponds to an
integer, else false. E.g.,
isInteger ("42") returns true.
isInteger ("42a") returns false.
• The code is executed with the following keyboard input by the user:
42a [Enter] 42 [Enter]
where [Enter] means one press of the standard Return/Enter key.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F95b5a871-62fa-479b-89b7-393477eed51e%2F87b3e098-e2f9-4de7-813b-e09c4503232c%2Fr3tdzbh_processed.png&w=3840&q=75)
