Assuming class A has a method named getXXX() and class B is a sub class of class A. Now, if we write a method with the same name getXXX() in class B, with exactly the same signature as class A, it is called overriding a method. The method getXXX() in class A becomes the overridden method.
In Java, or in any object oriented language such as C++, a method defined in super (parent) class does not need to be defined in a subclass, because that is the primary purpose of inheritance. Object oriented programming allows you to define and declare a class that implements the behavior for an object. Inheritance allows you to refine, or subclass, that class by "reusing" all of the functionality of the parent class into the sub class, adding additional definition and declaration for the sub class. If the subclass needs to change a parent class method, it can overload that method. This is called abstraction.
If the method is static you can do this way: Classname.method() If the method is not static then you would have to instantiate the class that contains this method and then call it using that object. Classname obj = new Classname(); obj.method()
Yes - in Java, every class has this method, which is inherited from the Object class. Often, the inherited method does nothing particularly useful, but you can override it with your own implementation.
Method overriding is similar to method overloading, with a small difference. In overriding, a method in a parent class is overridden in the child class. The method in the child class will have the same signature as that of the parent class. Since the method in the child class has the same signature & name as the method of its parent class, it is termed as overriding. In situations where you may have to explicitly call the parent class method you can use the "super" keyword and for explicitly calling the current objects method you can use the "this" keyword.

The teacher is more active and students are passive, but he also uses question answers to keep them attentive in the class. It is used to motivate, clarify, expand and review the information. By changing Ms Voice, impersonating characters, shifting his posing, and using simple devices, a teacher can deliver lessons effectively.

Students should use respectful and formal language when speaking to teachers in class.

Lecture classes typically involve the instructor presenting information to the students, who listen and take notes. In a general psychology lecture class, students may learn about various psychological theories, concepts, and research findings.
A lecture forum is a type of online community set up for students to discuss class material. In these educational forums, students can discuss class material with each other.
