Question

类方法 和实例方法区别

实例方法，总是从对象创建时所属的类开始，沿类层次向上查找。
Manager man=new Manager();
Employee emp1=new Employee();
Employee emp2=(Employee)man;
emp1.computepay();//调用Empolyee类的方法
man.computepay()；//调用manager
emp2.computepay();//调用manager

对于类方法，查找在编译时进行，所以总是在引用变量声明时所属类中进行查找
Manager man=new Manager();
Employee emp1=new Employee();
Employee emp2=(Employee)man;
man.expenseallow();//in manager
下面方法是static
Employee.expenseallow();//in employee
Manger..expenseallow()//in manager
emp1.expenseallow();//in employee
emp2..expenseallow();in employee

object
person
employee
manager

Answer 1

静态变量与实例变量的修饰词
静态变量由static修饰，实例变量不需要static修饰？
