This document provides an overview of basic Java programming concepts including Java as a programming language, examples of Java programs, flow charts, pseudocode, and algorithms. It describes Java as a popular, general-purpose programming language owned by Oracle that is object-oriented. It lists examples of NASA World Wind, desktop apps, financial software, and websites built with Java. It also defines and provides examples of flow charts, pseudocode, and algorithms, including a flow chart, pseudocode, and algorithm for adding two numbers.

3. Basic Of Java programming

4. • Java is a popular general – purpose.
programming language and computing
platform. It is fast, reliable and secure.
• It is owned by the famous American.
multinational computer technology
corporation and Java runs on 3 billion
devices in the worldwide.
• Object Oriented Programming is one of.
the popular programming styles.
A complex problem will divide in small s
ets by creating and this makes the code
reusable, and Java is also a Object Orie
nted Programming Language.

5. Some Examples Of Java Programming Language
⚙ Nasa World Wind is a free and open source virtual
globe and it is allow developers to quickly and easily
create interactive visualizations of 3D globe.
⚙ Famous desktop applications like Gmail, Eclipse,
NetBeans and Intellij Idea are created with the use of
java.
⚙ Murex is a famous financial software like trading,
treasury built in java.
⚙ Amazon also use java in addition of other languages.
⚙ Ebay, LinkedIn, Google Plus, GTalk are uses Java
extensively.
⚙ Some of Famous Websites Written in java are
betbuy.com, ae.com, tesco.com, express.com.

7. Flow Charts

8. • Flowcharts to document business processes came into use in the 1920s and introduced by Frank and
Lillian Gilbreth.
• Flowcharts are popular for computer programs and algorithms of all kinds and programmers are still
used for programming today.
• Flowchart is a diagram that depicts a process, system or computer algorithm.
• They are widely used in multiple fields to document, study, plan, improve and communicate often
complex processes.
• Flowcharts are use rectangles, oval, diamonds and numerous other shapes and along with connecting
arrows to define flow and sequence.

9. Some Symbols of Flowcharts
- Process Symbol and it’s represents a process. .
- Decision Symbol and it’s indicates yes/no or true/false and may then split off
into different branches.
- Start/ End Symbol and it’s represents start points, end points and potential
outcomes of paths.
- Arrows and it is a connector that shows relationship between the represented
shapes.
- Input / Output Symbol and it represents data available for input / output

11. Pseudocode
s

12. • Pseudocode is an artificial and informal language that helps programmers develop algorithms.
• The purpose of using pseudocode is that it is easier to for people to understand.
• Scientific publications related to computer science and numerical computation often use pseudocode
in description of algorithms, so all programmers can understand it.

13. Step 01: Begin
Step 02: Input the first number
Step 03: Input the second number
Step 04: Add the two numbers
Step 05: Output the sum
Step 06: End
Pseudocode of Adding Two Numbers

14. Algorithms

15. An algorithm is procedure or formula for solving a problem, based on conducting sequence of specified
actions. A computer program can be viewed as an elaborate algorithm.
It is a precise, systematic method for producing a specified result and everyone uses and invents algorithms
all the time to solve problems.
The agent running the algorithm does not need to be a computer.

16. Algorithm of Adding Two Numbers
Step 01: Start
Step 02: Get two numbers in x and y
Step 03: Add a and b and store in c
Step 04: Display c
Step 07:End
