title: JOptionPane.showInputDialog() questions
body: <p>I am just beginning Java programming tonight (although I am a long time C++ coder). </p>
  
  <p>I am experimenting with the <code>JOptionPane.showInputDialog()</code> function to gather user input.</p>
  
  <p>However, it keeps setting the z-order of the input dialog underneath my IDE, with no notification on the start menu that a dialog is even there. </p>
  
  <p>Is there any way to set options for it to appear at the top of the z-order, or perhaps even system modally?</p>
  
  <p>Also, is there any way to limit the types of characters that can be entered into the text box of the input dialog, such as numeric types only?</p>
  
  <p>Thanks for the help</p>
