Java中如何實現列表對象(List)的靈活查找？/java中Listgen根據某個元素獲取對象

public class Customer {

      private int id;

      private String name;

//其他省略 }

//建立測試數據

List<Customer> customers = new ArrayList<>();

     customers.add(new Customer(1, "Jack"));

     customers.add(new Customer(2, "James"));

     customers.add(new Customer(3, "Kelly"));

//實現查找，找到則返回匹配的對象，找不到則返回null

Customer james = customers.stream() .filter(customer -> "James".equals(customer.getName())) .findAny() .orElse(null);
