java - 如何显示 arraylist 中的删除节点？

Question

public static void deleteEmployee(int empId) {
        Iterator<Employee> iterator = list1.iterator();
        while (iterator.hasNext()) {
            if (iterator.next().getEmpid() == empId) {
                System.out.println("The name of whose details deleted is  ::");
                iterator.remove();
            }
        }

    }

在这里，我试图根据员工 ID 从数组列表中删除节点。但在删除之前，我想显示特定员工的详细信息。我怎样才能做到这一点？

Answer 1

将员工存储在临时变量中怎么样？

public static void deleteEmployee(int empId) {
    Iterator<Employee> iterator = list1.iterator();
    while (iterator.hasNext()) {
        Employee employee = iterator.next();
        if (employee.getEmpid() == empId) {
            System.out.println("The name of whose details deleted is  ::" + employee.getName()); // or whatever property in employee
            iterator.remove();
        }
    }

}

Answer 2

Iterator这与or无关List。

看看Employee：它是否有一个toString()打印细节的实现？如果没有，它的属性是否有吸气剂？将这些与System.out.println.
