What is the use of package in JAVA?

broadly speaking, the "package" facility helps organize a large codebase into multiple packages which can be maintained in separate directories. Java compiler determines the directory name where source code of a package is kept, based on the package name. Also used by Java to determine the classes,... ...more
broadly speaking, the "package" facility helps organize a large codebase into multiple packages which can be maintained in separate directories. Java compiler determines the directory name where source code of a package is kept, based on the package name. Also used by Java to determine the classes, variables, methods that can be accessed by a class. Classes, etc. in a package are accessible to other classes in same package (by default). See details of "Java access modifiers" for more info on these restrictions or allowances.

Why using Overriding in Java ?

allows a different implementation of a method without requiring parent class to be abstract. Example: Parent class provides default implementation for a category of devices without knowledge of specific manufacturer, etc. details.

Example: Parent class provides default implementation for a category of devices without knowledge of specific manufacturer, etc. details. And child class methods override some/all methods to model specific behavior for devices from specific manufacturer. Note that, the parent class here is not required to be abstract -- it models a "general" device with default behavior.

What is 'this' in Java?

You will see the 'this' reference inside a method source code. It refers to the object in whose context the method is called.. So, when there is a call like objectA.methodM(), then, a 'this' reference inside methodM() refers to the objectA. Example: a 'this' reference inside the method getArea()... ...more

Example: a 'this' reference inside the method getArea() of a Circle class refers to the particular Circle object for which the getArea() is called. You will realize that 'this' can be called only inside an instance method not a class method when you understand 'instance method' and 'class method'
