Java 21 - Record Patterns: Exemplos Práticos

Projeto baseado no tutorial:

A versão 21 do Java foi aprimorada com padrões de registro (Record Patterns) para desconstruir valores de um objeto record. Padrões de registro chegou a linguagem para permitir uma forma poderosa, declarativa e combinável de navegação e processamento de dados.

public static void main(String[] args) {  
  Vehicle vehicle = new Vehicle("Honda", "Fit 1.4", "JAV-1621");  
  
  if(vehicle instanceof Vehicle(String brand, String model, String licensePlate)) {  
        System.out.println(brand + " - " + model + ": " + licensePlate);  
  }  
  
  if(vehicle instanceof Vehicle(var marca, var modelo, var placa)) {  
        System.out.println(marca + " - " + modelo + ": " + placa);  
  }  
}
