Violation Code Sample
class Person implements Cloneable { private String name; public Person(String name) { this.name = name; } public Person clone() { return new Person(this.name); // violation } }
Fixed Code Sample
class Person implements Cloneable { private String name; public Person(String name) { this.name = name; } public Person clone() { try { return (Person)super.clone(); // FIXED 'clone' correctly calls 'super.clone' } catch (CloneNotSupportedException e) { throw new AssertionError("Should never happen"); } } }
