Push Down

In software engineering, Push Down refactoring involves moving a method from a superclass into a subclass. Compare the following Java classes before and after the Push Down refactor is applied:

public class SuperClass{ void methodA() { //do something } void methodB() { //do something else } } public class SubClass extends SuperClass { void methodC() { //do something } }

After the Push Down refactor is applied:

public class SuperClass{ void methodA() { //do something } } public class SubClass extends SuperClass{ void methodB() { //do something } void methodC() { //do something else } }
