Java - Why is there a 'cannot find symbol' error despite having already declared the variable?

Question

Code: https://code.sololearn.com/cq3SmFJGQC2X/#java

The error seems to occur on line 27.

Answer 1

Try putting the scanner and int number; before the do while loop and inside just say, number = scanner.nextInt();

Answer 2

Since you declared and initialized the scanner and number variables inside the do block it can only be accessed in the do block but you are trying to access it in the while statement hence you are getting the error. To fix it just do as Avinesh said. To get more information on this visit: https://www.google.com/amp/s/www.geeksforgeeks.org/variable-scope-in-java/amp/
