This document provides an introduction to object-oriented programming concepts like classes, objects, methods, and attributes. It discusses Java and how to set up an Android development environment. It also covers basic Android concepts like activities and the activity lifecycle. The key topics are:
- An introduction to object-oriented programming (OOP) principles like classes, objects, inheritance and interfaces.
- A brief overview of Java and how to write a simple "Hello World" program.
- Instructions on setting up an Android development environment and running a first Android app.
- An explanation of activities and the importance of the activity lifecycle in Android.
Object Oriented Concepts required to know about the Android Application Programming are discussed over here. Get the most of the details about each and every concept of OO paradigm so you can use them very well in Android Application Programming.

Exploring Ceylon with Gavin King - JUG BB Talk - Belrin 2014hwilming
The slide to the Java User Group Talk Exploring Ceylon from Gavin King.
Abstrakt:
Ceylon is a new programming language designed for writing large programs in teams. The language emphasizes readability, modularity, typesafety, and tooling. Ceylon programs execute on Java and JavaScript virtual machines. In this session, Gavin King will talk about the ideas behind Ceylon and demonstrate the language, its type system, its module architecture, and its IDE.
Speaker:
Gavin King leads the Ceylon project at Red Hat. He is the creator of Hibernate, a popular object/relational persistence solution for Java, and the Seam Framework, an application framework for enterprise Java. He's contributed to the Java Community Process as JBoss and then Red Hat representative for the EJB and JPA specifications and as lead of the CDI specification.
Now he works full time on Ceylon, polishing the language specification, developing the compiler frontend, and thinking about the SDK and future of the platform. He's still a fan of Java, and of other languages, especially Smalltalk, Python, and ML.
Introduction to Java programming - Java tutorial for beginners to teach Java ...Duckademy IT courses
Check out the course: https://www.duckademy.com/course/java-programming Learn Java from scratch in an easy and entertaining way. The Easy-to-follow Java programming course on Duckademy was made for beginners. In this course we start at the very basics (from zero) and go through lots of interesting exercises and analogies that will take you to an advanced level. By the end of the course you will have all the knowledge needed to move on and specialize in Java. The course is easy to follow and things are well explained. Furthermore, to make your learning easier and more enjoyable throughout the course we will develop a nostalgic, text-based fantasy game.
The course is recommended to anyone who wants to learn Java. Ideal for those who are new to programming, but it can be useful and enjoyable for people who want to switch to Java from a different programming language.
By the end of the course you will be able to build simple, but fully functional programs. You will also gain all the knowledge needed to specialize in Java and become a well-payed Java expert later on.

Java history, versions, types of errors and exception, quiz SAurabh PRajapati
this ppt contains history and basic facts of object oriented programming language java, difference between JIT, JVM, JRE and JDK. it also having information about different versions of java. advantages over other language, difference between error and exception with its types is also included. explanation of final variable and string to int conversation is also added. in the end some twisted question of it which sharpen the knowledge of its basic are added. beyond this some programming examples with output is there too. hope u find it useful...!! thanku..!!
This slide aims to describe the basic introduction about Java with the Eclipse platform. Many examples were applied in order to understand the main features of programing by using Java.

EESTEC Android Workshops - 103 The Internet and JSON
EESTEC Android Workshops - 101 Java, OOP and Introduction to Android
1. EESTEC Android
Workshops
101 - Introduction to OOP, Java and Android
2. What we’ll cover today
EESTEC, Android, it’s APP to you!
Introduction to OOP
Introduction to Java
Setting up the Android Environment
Running your first App
6. Basic Concepts
Class - Blueprint, used to create instances of
itself
Object / Instance - Instances are class
occurrences
Method - Function / Procedure of an object
or class
Attribute - Fields with values (objects) in a
object
7. Pros
Code decoupling, enforces code reusability
Associates data structures with their related
methods
Makes real-world object representation
easier
16. Java, at a glance
C-like syntax
Created in Sun Microsystems,
by James Gosling
Now acquired by Oracle
17. Hello, Java World!
public class HelloJava {
public static void main(String[] argv) {
System.out.println(“Hello, Java World!”);
}
18. Great Things about Java
Has a garbage collector, simply do not care
about memory leakage!
Your program fails, except exceptions!
Is platform-independent, runs in it’s own VM,
the JVM
19. Garbage Collector
Java objects leave in
a heap
When the Garbage
Collector needs to
release memory, it
starts removing
dangling objects
Slightly pauses the
application threads
20. Exceptions
Java gives you the chance to get a bit off
track, but then makes sure you can handle
unwanted situations
You can try something weird and if it turns
bad, you handle the exception
21. Example
try {
something that might destroy the universe
catch (EarlyDestructionExcpetion e) {
save the world
}
23. The mystery, explained...
Complete software stack
Operating System
Middleware
Key Applications
Open Source Developed by the Open Handset
Alliance
Fastest growing market
Platform with the most devices activations
26. Activity
Creates a window, so that the user can
interact with the app
Can communicate with the system
Controls the higher level of the user
interface
27. Activity, get a
life!
The lifecycle of an Activity is
really important.
Listen to Lifecycle events, in
order to save and reproduce
the state of the app
28. Tasks for next time
1. Create an application 3. When the button is
that asks for the user’s pressed, a clear button
name appears that resets
everything
2. Then, after hitting a
button, it populates a Hint: Check the
text view with a following classes:
personalized message TextView, EditText,
for the user Button and
OnClickListener
