Why do need to use new Random() instead of just Random Randomnum? : <p>I'm currently doing the mooc java course and I'm not able to understand why exactly we need to include new Random() part after declaring a new new variable randomVar with the class type Random?</p>

<pre><code>   private Random randomNum = new Random(); // Why this? 

   private Random randomNum; //Instead of this? 
</code></pre>
