JavaSE-抽象类讲述
抽象类是一种引用数据类型抽象类语法：修饰符+abstract +抽象名{}抽象类可以被继承抽象类中，可以有构造super()，实列方法，实列，静态，局部变量非抽象类继承抽象类方法，必须实现抽象类中的抽象方法抽象类方法语法：public abstract void fangFa01();抽象类可以多态 public class Dem04 { public static void main(String[] args){ ChouXiang05 x = new FeiChouXiang(); x.fangFa01(); } } abstract class ChouXiang05{ int bianHao; String xingMing; double yuE; public ChouXiang05(){}; public ChouXiang05(int bianHao,String xingMing,double yuE){ this.bianHao= bianHao; this.xingMing =xingMing; this.yuE = yuE; } public abstract void fangFa01(); } class FeiChouXiang extends ChouXiang05{ public FeiChouXiang(){ }; public FeiChouXiang(int bianHao ,String xingMing, double yuE){ super( bianHao, xingMing , yuE); } public void fangFa01(){ System.out.println("抽象方法被继承"); } }
