title: is this bad programming ? scanner as global variable
body: <p>Is it considered bad programming practice to have an input scanner (such as a keyboard ) declared as a global var for a class? such like:</p>
  
  <pre><code>private static Scanner input  = new Scanner(System.in);
  </code></pre>
  
  <p>Im working with alot of input from various methods, and just seems alot easier then having to send the keyboard to each method</p>
