title: Java Question mark inside println()
body: <p>I'm trying to make a program that solves equations, i want the answer to be displayed in the right way, if the number is negative, to display -x and not +-x,
  for example,
  Eq1: 4x-3 and not 4x+-3, but when it is positive to display 4x+3. I can't use the plus sign inside the quotations.
  I wanted to use the ? : operator. 
  I tried something like this</p>
  
  <pre><code>System.out.println("Eq1: "+ ((a11&gt;0) ? (+ "+" + (int)a11) : + (int)a11) +"*x1+");
  </code></pre>
  
  <p>This line is supposed to print the negative number (i.e. it will be -2*x1) and if it's positive it should display the + sign and add the number, but it gives me an error around the + "+" +</p>
  
  <p>Any thoughts? Thanks!</p>
