Question

我需要打印用户输入的员工的详细信息。到目前为止，我能得到的只是名字。任何人都可以帮我一把吗？

EmployeeStore

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

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

用法

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

您正在打印密钥，而不是密钥中存储的值。

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

假设Employer类已定义了toString（）方法。

HashMap的搜索方法
