我正在做一个员工商店。employeeStore 中的删除功能不起作用。它没有删除员工,而是什么都不做,任何人都看不到任何错误。
这是我的代码:主要
case 3:
System.out.println("Delete by Name.");
Employee employeeDelete = MenuMethods.userInputByName();
Store.searchByName(employeeDelete.getEmployeeName());
System.out.println("Your choice is: "+ employeeDelete);
Store.remove(employeeDelete);
break;
删除方法
// ---------------------------------------------------------------------------------------
// Name: Remove.

public Employee remove(Employee key) {
// Remove the Employee by name.
if (map.containsKey(key))
return map.remove(key); // if its there remove and return
else
return null; // if its not there return 0x00000000 address
}
