Cracking the #Java #Coding #Interview - Question 241: What is pattern matching?

In recent days(especially after rust become famous). Destruction is considered as a must feature for pattern matching. It's better to introduce record destruction pattern more. e.g. we can have switch (expr) { case Expr.Add(Expr.Int(var x), Expr.Add(Expr.Int(var y), Expr.Int(var z))) -> x + y + z; }
