What is a Flowchart?

• ​is a visual representation of an algorithm. It contains shapes describing how an algorithm or program operates. Each command is placed in an appropriate shape, and arrows are used to direct program flow.

History of Java

​What is Java?

​Why use Java?

​Who developed Java?

​What is Java?

• ​is a visual representation of an algorithm. It contains shapes describing how an algorithm or program operates. Each command is placed in an appropriate shape, and arrows are used to direct program flow.

​Why use Java?

• ​It is easy to learn and simple to use

• ​It is secure, fast and powerful

• ​Java is an object oriented language which gives a clear structure to programs and allows code to be reused, lowering development costs

• ​Close to C++ and C#, which allows programmers to switch to Java or vice versa.

​Who developed Java?

​Sun Microsystems funded an internal research project “Green” to investigate this

opportunity.

​

- Result: A programming language called “Oak”

​-Java was developed by James Gosling, who is known as the father of Java, in 1995.

​Why is it named "Oak"?

• ​Oak is a symbol of strength and chosen as a national tree of many countries like the U.S.A., France, Germany, Romania, etc.

• ​

• ​Java is an island in Indonesia where the first coffee was produced (called Java coffee). It is a kind of espresso bean. Java name was chosen by James Gosling while having a cup of coffee nearby his office.

​Java Applications

• ​Desktop Applications

• ​Web Applications

• ​Enterprise Applications - banking app

• ​Mobile

• ​Embedded System

• ​Smart Card

​Java

• ​A complete programming language developed by Sun

  Can be used to develop either web based or stand-alone software

  Many pre-created code libraries available

  For more complex and powerful programs

• ​A small language that’s mostly used for web-based applications (run through a web browser like Internet Explorer, Firefox, Safari, Chrome)

  Good for programming simple special effects for your web page e.g., roll-overs

​JavaScript

Compiled programs with different operating systems

-Interpreter
