title: Scanner input == null?
body: <p>I am trying to say if you enter a character it will do this; else if scanner input == null do this instead. I'm not getting any syntax errors, I just need to know how to word this so that if you don't enter any characters and hit ENTER then it will go to my default settings. 
  Here is what I have so far. </p>
  
  <pre><code>Shape sq = new Square(10);
                  System.out.println("Choose character to fill your shape. A-Z, a-z, ! # $ % &amp; ( ) * + Press ENTER.");
                  characterChoiceSquare = input.next();
                  if(characterChoiceSquare == input.next())
                  {
                      for(int m = 0; m &lt; shapeChars.length; m++)
                      }
                      {
                          if(characterChoiceSquare.equals(shapeChars[m]));
                          {
                              char[] c1 = characterChoiceSquare.toCharArray();
                              char[] shapeCharacter = new char[sq.getSizeInt()];
                              for(int i = 0; i &lt; sq.getSizeInt(); i++) 
                              {
                                  shapeCharacter[i] = c1[0]; // repeat the char input to fit shapeString
                              }
                              string = String.valueOf(shapeCharacter); //assign the value of the arraylist to shapeString
  
                              shapeString += string + "\n";
  
                              System.out.print(shapeString);
                          }
                      }
                  }
                  else if(characterChoiceSquare == null)
                  {
                      System.out.print(sq.displayCharacters());
                  }
  </code></pre>
