java util classes
<p>Util class in java can be made in two ways  </p>

<pre><code>class Utils  
{   
  public static ReturnType someUtilMethod(  
 // ...   
}    
</code></pre>

<p>and execute util method by </p>

<pre><code>Utils.someUtilMethod(...);
</code></pre>

<p>Or I can make   </p>

<pre><code>class Utils  
{  
  public Utils(){}     
  public ReturnType someUtilMethod(  
 // ...   
}  
</code></pre>

<p>and execute util method by   </p>

<pre><code>new Utils().someUtilMethod(...)  
</code></pre>

<p>What way is better? Are some differences between this ways?</p>
