属性和方法组成类
package com.oop;
//属性和方法组成类
public class Student {
//属性
String name;
int age;
//方法
public void study(){
System.out.println(this.name+"在学习");
}
}
类是抽象的,可以用new实例化
package com.oop;
public class Application {
public static void main(String[] args) {
//类是抽象的,需要实例化,new
Student xiaoming = new Student();
//类实例化后会返回一个自己的对象
//xiaoming对象 就是一个Student类的具体实例
xiaoming.name="小明";
xiaoming.age=5;
System.out.println(xiaoming.name);
System.out.println(xiaoming.age);
}
}
