请帮我看看这个通配符泛型错在哪里？

你把方法定义到main函数干嘛？？
[解决办法]

        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);
                 

 
        }   
                 public static void printC(A<? extends Employee> p)
                {
                        Employee first = p.getFirst();
                        Employee second = p.getSecond();    
                }

语法错误
[解决办法]
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);

 

}
public static void printC(A<? extends Employee> p)
    {
    Employee first = p.getFirst;
    Employee second = p.getSecond;
    }
}

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;
}

class Employee
{
String name;
double salary;

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

[解决办法]
你这方法不要在main方法里面定义。。
[解决办法]
<? extend T> p 表示 p只能是T类型或T的子类的类型
<? super T> p  表示 p只能是T类型或T的父类类型直至Object类型
