I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Description

1. Member variables, compile to the left, run to the left

2. Construction method. The construction of the subclass accesses the parent class construction by default.

3. Member method, compile to the left, run to the right

4. Static method, compile to the left, run to the left

Example

Package day09;/** member variables: * compile to the left (parent class), run to the left (parent class) * * / class Demo_PolyMorphic {public static void main (String [] args) {Father f=new Son (); System.out.println (f.num); Son s=new Son (); System.out.println (s.num);}} class Father {int num=10;} class Son extends Father {int num=20 } these are all the contents of the article "how to access members of java Polymorphism".
