title: unreported exception IOException... must be caught or declared to be thrown
body: <p>I'm getting this error: "unreported exception IOException; must be caught or declared to be thrown" in this piece of code: </p>
  
  <pre><code> a = Double.parseDouble ( kb.readLine () ) ;
   b = Double.parseDouble ( kb.readLine () ) ;
   c = Double.parseDouble ( kb.readLine () ); 
  </code></pre>
  
  <p>Here is the rest of the code:</p>
  
  <pre><code> package quadratic.java;
  
  
  /**

   * @author Painfulmono
   */
   import java.io.*;
   public class QuadraticDriver {
  
       BufferedReader kb = new BufferedReader 
                      (new InputStreamReader (System.in));
   public static void main (String [] args){
  
       double a, b, c;
  
       a = Double.parseDouble ( kb.readLine () ) ;
       b = Double.parseDouble ( kb.readLine () ) ;
       c = Double.parseDouble ( kb.readLine () ); 
  
       QuadraticJava q1 = new QuadraticJava (a, b, c);
  
       q1.solve();
  }
  </code></pre>
  
  <p>}</p>
  
  <p>How would I get it declared?</p>
