Practical pattern regarding equals()

Posted by Vjekoslav Nesek on 16 Sep 1998, 7:30 AM

You can make your code more elegant and gain some perfomance
improvements by implementing equals in a following manner:

class A {

/* ... */

public boolean equals(A a) {
/* ... */
}

public boolean equals(Object o) {
return o instanceof A? equals((A) o) : false;
}
}
