Answer 1

Your variable item has scope to the do while loop it is defined in.

int exit = 0;
String item = null; // <-- Add this

then change your loop

do {
    System.out.println("Enter item number: ");
    item = input.next(); // <-- Defined outside this scope now.
    if (ValidateItem(item) == true) {
        if (Integer.parseInt(item) <= 4 && Integer.parseInt(item) >= 1) {
            exit = 1;
        } else {
            System.out.println("Enter an item number between 1 and 4");
        }
    } else { // <-- just use else
        // if (ValidateItem(item) == false) {
        System.out.println("Enter an item number between 1 and 4");
    }
} while (exit == 0);

Answer 2

The item variable is declared in the first do while loop Hence you can access it inside the do while loop To access the item in the scope of the function, you should declare it before the do while loop, so that it can be accessed in the if(item==1) statement
