Inheritance (static and non-static methods)

After the subclass is instantiated, the method in the parent class can be directly called through the subclass.

Call:

1. That is, son = new son (); after the subclass is instantiated, only non-static methods in the subclass and parent classes can be called.

You can call the son. dfangfa () method in the subclass ();

Son. dfun ();

2. Do not instantiate the object during the call. Only static methods in the subclass and parent classes can be used.

Son. jfangfa ();

Son. jfun ();

Public father {public void dfun () {// Implementation} public static void jfun () {// Implementation }}

Public son {public void dfangfa () {// Implementation} public static void jfangfa () {// Implementation }}
