面向对象(学生类)

class Student{
 String name;
 int age;
 String addrss;
  void study(String name){
  System.out.println("学生"+name+",爱学习!");
 }
 void eat(String name){
  System.out.println(name+"学习累了,吃饭!");
 }
  void sleep(String name){
  System.out.println(name+"学习累了,睡觉!");
 }
}
public class StudentDemo{
 public static void main(String [] args){
  Student s = new Student();
  s.study("zx");
  s.eat("zzx");
  s.sleep("zxx");
}
}
结果:
学生zx,爱学习!
zzx学习累了,吃饭!
zxx学习累了,睡觉!
