A class’s testability is improved through composition over inheritance. If a class is comprised of another class, it is simple to create a mock object to simulate the combined class for testing purposes. Even while Composition and Inheritance both let you reuse code, Inheritance has the drawback of breaking encapsulation. If the function of the subclass depends on the superclass’s action, it suddenly becomes vulnerable. Sub-class functionality may be broken without any alteration on the part of the super-class when its behaviour changes. A programme is a non-active entity that includes the collection of codes necessary to carry out a specific operation. When a programme is run, an active instance of the programme called a process is launched.

In Java, static as well as private method overriding is possible. Comment on the statement.
