The code defines a Bike class with a final integer field speedlimit that is initialized to 70 in the constructor. The main method creates a new Bike object, which prints out the maximum speed limit of 70.
The code defines a Vehicle class with a constructor that prints "Vehicle is created". It also defines a Bike class that extends Vehicle, with its own constructor that first calls the Vehicle constructor using super(), then prints "Bike is created". The main method creates a Bike object, which results in output showing that both the Vehicle and Bike constructors were invoked.
Phase 1 of the Cisco UCS implementation was completed, migrating approximately 130 VMs to the new infrastructure with only minor issues. Phase 2 will focus on migrating additional workloads like Citrix, SQL clusters, and call management systems. The UCS implementation has already reduced the organization's colocation costs by $1,100 per month through decreased rack and power usage, with expected annual savings of $13,000 after Phase 1 and over $30,000 after Phase 2. Initial performance monitoring also shows efficiency gains from lowered CPU and memory utilization within the virtualized environments.
The document discusses using the final keyword in Java to prevent method overriding and inheritance. It provides examples of declaring final classes, methods, and variables. Final classes cannot be subclassed, final methods cannot be overridden, and final variables are effectively constants. The document also recaps multi-level inheritance and defines the three main uses of final - to create named constants, prevent overriding, and prevent inheritance. Frequently asked questions and a short quiz are included at the end.
The document discusses Java wrapper classes, nested classes, local classes and anonymous classes. It provides details on the eight primitive wrapper classes in Java, their methods and how they are used to wrap primitive types. It also explains autoboxing and unboxing features. The document further elaborates on nested, local and anonymous classes in Java - their definitions, usages and examples.
Super keyword is a reference variable that is used for refer parent class object. Super keyword is used in java at three level, at variable level, at method level and at constructor level.
The super keyword in Java is used to refer to the immediate parent class and its members. It can be used at the variable, method, and constructor level. For example, in a Bike class that extends the Vehicle class, using super.speed in the display() method will access the speed variable of the parent Vehicle class and output 100, rather than the speed variable defined in Bike which has a value of 200.
The document discusses the static keyword in Java and its uses for variables, methods, blocks and nested classes. It explains that static members belong to the class rather than instances, and provides examples of static variables, methods, blocks and how they work. Key points include static variables having only one copy in memory and being shared across instances, static methods that can be called without an instance, and static blocks that initialize static fields when the class loads.
Static blocks are blocks of code prefixed with the 'static' keyword that get executed only once when the class is loaded. They are used to initialize static variables. Final variables prevent modification of their contents once initialized and must be initialized when declared, allowing for typed constants. Static blocks and final variables demonstrate important concepts in Java including static initialization and constants.

The final keyword in Java is used to define entities that cannot be changed, including variables, methods, and classes. Final variables are read-only and cannot be reassigned, final methods cannot be overridden in subclasses, and final classes cannot be subclassed themselves. Using final improves performance and prevents accidental changes to values or overriding of methods that were not intended to be overridden.
Constructors and functions can be overloaded by having the same name but different parameters, allowing multiple implementations. Function overriding occurs when subclasses define functions of the same name and parameters as the parent class. Abstract classes contain abstract methods that are undefined, preventing object creation, and must be implemented in subclasses.
Method overriding allows a subclass to provide a specific implementation of a method that is already provided by its superclass. The subclass method must have the same name, parameters and return type as the superclass method. This allows the subclass to modify the behavior as needed and is how polymorphism is implemented. The super keyword can be used to call the superclass method from the overriding method.
Final keyword are used in java for three purpose;
1. Final keyword is used in java to make variable constant
2. Final keyword restrict method overriding
3. It used to restrict Inheritance

This document provides instructions for creating a password protected folder without using additional software. It involves copying code into Notepad and saving it as a .bat file. Running the .bat file will create a folder called "Gift" that is hidden and locked. Entering the correct password of "7448264" in the command prompt will unlock the folder and allow access to contents. The code uses batch scripting and commands to rename the folder with a long cryptic name, set attributes to hide and lock it, and check password input for access.
This Presentation is the intro. to java programming.
This presentation contain the basics of Java with example in simple language.
This presentation clear your all concept about programming in java and then you can easily make programs in java.
This Java program uses a for loop to check if a user-input number is prime or not. The program takes the number as input, divides it by all integers from 2 to the number/2, and checks if any division results in a remainder of 0. If no remainders are 0, the number is prime and the program prints that it is prime; otherwise, it is not prime and the program prints that it is not prime.
The document shows an example of method overriding using abstract methods. It defines classes A, B, and C where B and C extend class A. Class A contains a getA() method that prints a message. Classes B and C override this method by defining their own getB() and getC() methods, with B calling the superclass method and both printing additional messages. The main method creates instances of B and C and calls their respective methods to demonstrate method overriding.
This document discusses how to achieve multiple inheritance in Java using interfaces. It defines two interfaces, Father and Mother, that each contain a float variable and method to get height. A Child class implements both interfaces and overrides the height method to calculate and print the average height from the interfaces. The code is tested in a main method that creates a Child object and calls its height method.
This Java program demonstrates method overriding. It defines a wallet class with dimensions and a salary method that returns 0. Monthly and annual classes extend wallet, overriding the salary method to return the product of the dimensions, and printing the appropriate salary text. The main method creates instances of each class, assigns them to a wallet reference variable, and calls salary to print the results.

This document contains code that implements inheritance and method overloading. It defines a base mob class with getmob and putmob methods to retrieve and display student roll number and name. The drive class inherits from mob and overloads getdrive and putdrive methods to also retrieve and display subject marks. The pen class inherits from drive and overloads getresult and putresult methods to calculate and display the total marks. The main method creates a pen object and calls its methods.
The document defines a Sum class with three overloaded add() methods that take in different parameter types (two ints, three ints, and an int and float) and return the sum. It then creates a main method in an Overloading class that creates a Sum object and calls each add() method, passing different parameters to demonstrate function overloading.
This code defines a class called "different" with integer instance variables a, b, and c. It initializes two objects of this class, mob and code, with different values for a, b, and c. It then calculates the product of a, b, and c for each object and prints the results.
This document demonstrates type conversions in Java by writing a program that converts an int to a byte, a double to an int, and a double to a byte. It defines a main method that declares the variables, performs the conversions by casting the values, and prints the original and converted values to show the results of the conversions.
