I've created a do while loop that does insert items into an array list like I want it to but the problem is the output to console. I want the user to enter items into an array so I have a prompt like so:
As you notice it does not print Enter a[2]: to the correct part of the screen, it's like it skips the second iteration to print the prompt yet it still stores to in array[2]. Here is my code:
The problem is the next part of my code is picking up the letter x that is typed in last to end the while loop and runs the last else statement to throw back x is not an option!
You need to write down the boolean expression after while (... on a sheet of paper and explain to yourself exactly what it means.
You would do well to find the String.toUpperCase() and toLowerCase() methods.
You would do well to find about how to use a while loop and the hasNextInt method of Scanner to validate int input.
Seriously? That's what you're going with? I prefer this tiny ad:
