Reports instantiation of utility classes using the <code>new</code> keyword.
|
|
<p>
|
|
In utility classes, all fields and methods are <code>static</code>.
|
|
Instantiation of such classes is most likely unnecessary and indicates a mistake.</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
class MyUtils {
|
|
public static double cube(double x) {
|
|
return x * x * x;
|
|
}
|
|
}
|
|
class Main {
|
|
public static void main(String[] args) {
|
|
// Instantiation of utility class
|
|
MyUtils utils = new MyUtils();
|
|
}
|
|
}
|
|
</code></pre>
|
|
<p>
|
|
To prevent utility classes from being instantiated,
|
|
it's recommended to use a <code>private</code> constructor.
