how can i use java scanner in while loop
<p>This is what I have so far:</p>

<pre><code>int question = sc.nextInt(); 

while (question!=1){

    System.out.println("Enter The Correct Number ! ");

    int question = sc.nextInt(); // This is wrong.I mean when user enters wrong number the program should ask user one more time again and again until user enters correct number.
    // Its error is : duplicate local variable

}
</code></pre>
