类、对象(oop)
```javapublic class oopDemo6Student {
String name;
int age;
public void study(){
System.out.println(this.name+"在学习");
}
}
//person--->名字、生日、身高、体重
//类(抽象)--->对象、属性(实例)
在这里插入代码片
~~~java
public class oopDemo6 {
public static void main(String[] args) {
oopDemo6Student oopDemo6Student = new oopDemo6Student();//new实例化
//类实例化后会返回一个自己的对象!
//oopDemo6Student对象就是一个oopDemo6Student类的实例!
oopDemo6Student luohz = new oopDemo6Student();
oopDemo6Student luozh = new oopDemo6Student();
luohz.name = "罗混子";
luohz.age = 21;
luozh.name = "hr";
luozh.age = 21;
System.out.println(luohz.name);
System.out.println(luohz.age);
System.out.println(luozh.name);
System.out.println(luozh.age);
}
}
```
