HashMap上的搜索方法

Question

我需要打印用戶輸入的員工的詳細信息。到目前爲止，我所能得到的只是名字。任何人都可以幫我一把嗎？

EmployeeStore

public void add(Employee employee) 
{  
    map.put(employee.getEmployeeName(), employee); 
} 

public Employee searchByName(String name) 
{ 
    System.out.println(name); 
    return map.get(name);  
} 

---

使用

EmployeeStore Store = new EmployeeStore(); 
Store.add(new Employee ("James O' Carroll", 18,"hotmail.com")); 
Store.add(new Employee ("Andy Carroll", 1171,"yahoo.com")); 
Store.add(new Employee ("Luis Suarez", 7,"gmail.com")); 
Store.searchByName("James O' Carroll"); 

Answer 1

正在打印的關鍵，而不是存儲在鍵的值。

public Employee searchByName(String name) 
{ 
    Employee employee = map.get(name);  
    System.out.println(employee.toString()); 
    return employee; 
} 

假設Employer類定義了toString（）方法。
