Utility class with 'public' constructor

Reports utility classes with public constructors.

Utility classes have all fields and methods declared as static. Creating a public constructor in such classes is confusing and may cause accidental class instantiation.

Example:

public final class UtilityClass {
  public UtilityClass(){
  }
  public static void foo() {}
}

After the quick-fix is applied:

public final class UtilityClass {
  private UtilityClass(){
  }
  public static void foo() {}
}
