title: new Obj, always or sometimes?
body: <p><strong>Should I always make new objects out of everything in java even if i know i will only use one?</strong></p>
  
  <pre><code> obj = new obj();
   obj.method();
  </code></pre>
  
  <p>or just</p>
  
  <pre><code>classOfobject.method(); 
  </code></pre>
  
  <p>Why should I bother with the creation of a new obj in a situation like this?    </p>
