Inheritance
Rahul Naveen
It is a mechanism in which one object acquires all the properties and
behaviors of a parent object.](https://image.slidesharecdn.com/java-250926132200-16dcb439/75/A-session-on-Java-Programming-for-beginners-12-2048.jpg)
A session on Java Programming for beginners
- 1. Java Beginners A Sessionon • B Y R A H U L N A V E E N
- 2. Why Java? 1.Works Everywhere(WORA) 2.Object Oriented Programming(OOP) 3.Scalable and Good community support 4.Runs in 3+ billion devices 5.Rich Standard Library LET'S LEARN MORE.. Rahul Naveen
- 3. More about Java •Java was developed by Sun Microsystems (now owned by Oracle Corporation) and released in 1995. • It's widely adopted in various domains, including web development, mobile app development, enterprise software, scientific applications, and more. • Java is platform independence, which means that Java programs can run on any operating system or platform that supports the Java Virtual Machine (JVM). Rahul Naveen

- 6. JVM v/s JREv/s JDK: Rahul Naveen Java Virtual Machine tasks are: • Loads code • Verifies code • Executes code • Provides runtime environment
- 7. Java Runtime Environment(JRE): RahulNaveen The Java Runtime Environment is a set of software tools that are used for developing Java applications.
- 8. Java Development Kit(JDK): Rahul Naveen JDK is an acronym for Java Development Kit. The Java Development Kit (JDK) is a software development environment which is used to develop Java applications.

- 10. Conditional Statement: Rahul Naveen Javaprovides three types of control flow statement: 1.Decision-Making statements - if statements - switch statement 2. Loop statements -do while loop -while loop -for loop -for-each loop 3. Jump statements -break statement -continue statement
- 11. OOPs (Object-Oriented ProgrammingSystem) Rahul Naveen Object-Oriented Programming is a methodology or paradigm to design a program using classes and objects. It simplifies software development and maintenance by providing some concepts: These are the main pillars of the OOPs concept: • Inheritance • Polymorphism • Abstraction • Encapsulation
- 12. class Employee{ float salary=40000; } classProgrammer extends Employee{ int bonus=10000; public static void main(String args[]){ Programmer p=new Programmer(); System.out.println("Programmer salary is:"+p.salary); System.out.println("Bonus of Programmer is:"+p.bonus); } } Inheritance Rahul Naveen It is a mechanism in which one object acquires all the properties and behaviors of a parent object.
- 13. Use of Inheritance? RahulNaveen • Code Reusability • Polymorphism • Method Overriding (so runtime polymorphism can be achieved).
- 14. Types of Inheritance: RahulNaveen Note: Multiple inheritance is not supported in Java through class.
