为什么这个泛型不成功？

[u010179812]

下面这个程序编译不通过。

import java.util.*;

public class Test2
{
		public static void main(String[] args)
		{
				Employee a = new Employee("abc", 2000);
				Employee b = new Employee("efg", 6000);
				
				A<Employee> c = new A<Employee>(a ,b);
                                    
		}	
}

class A
{
		public A(Object first, Object second)
		{
				this.first = first;
				this.second = second;	
		}
		
		public Object getFirst()
		{
				return first;	
		}
		
		public Object getSecond()
		{
				return second;	
		}
		
		public void setFirst(Object newValue)
		{
					first = newValue;
		}
		
		public void setSecond(Object newValue)
		{
				second = newValue;	
		}
		private Object first;
		private Object second;	
}

class Employee
{
		String name;
		double salary;
		
		public Employee(String name, double salary)	
		{
				this.name = name;
				this.salary = salary;	
		}
}

错误提示为

A类改为如下

 class A<T> {

        public A(T first, T second) {
            this.first = first;
            this.second = second;
        }

        public T getFirst() {
            return first;
        }

        public T getSecond() {
            return second;
        }

        public void setFirst(T newValue) {
            first = newValue;
        }

        public void setSecond(T newValue) {
            second = newValue;
        }
        private T first;
        private T second;
    }

你的Class A 得带上泛型的吧 Class A<T> { //... }

[快乐的小呆]

你要A类使用泛型，首先得Class A<T>{}

谢谢大家，果真像你们说的那样，我对泛型暂时是糊涂的。
