Java不支持多重继承吗？ [英] Does Java not support multiple inheritance?

问题描述

让我们接受两个类的实例

Lets us take instances of two classes

public abstract class Shapes
{
      public abstract void draw(Graphics g);

}

public class Rectangle extends Shapes
{
     public void draw(Graphics g)
     {
          //implementation of the method 
     }
}

这里的课程 Rectangle 具有扩展类 Shapes ，并且隐式地扩展了类 Object 。我知道没有其他扩展是可能的，但我们不能调用继承类 Shapes 和对象多重继承？ （因为从一个角度继承两个类是多重继承）

Here the class Rectangle has extended class Shapes and implicitly it extends class Object. I know no other extension is possible, but can't we call inherited classes Shapes and Object multiple inheritance? (Since inheriting two classes is multiple inheritance from one perspective)

推荐答案

它不是多重继承。您不是继承自 Shapes 和 Object ，您继承自 Shapes 这是一个对象 。

It isnt multiple inheritance. You are not inheriting from Shapes and Object, you are inheriting from Shapes which is an Object.

多重继承只有在你继承的情况下一次来自2个班级。

Multiple inheritance is only if you inherit from 2 classes at once.

public class Rectangle extends Shapes, Figures

Java中不允许这样做。

Which isnt allowed in Java.

您所指的是多级继承。谢谢@BhavikShah

What you are referring to is Multilevel Inheritance. Thanks @BhavikShah
