Introduction Of Java
- 2. Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. It is the most popular programming language for Android smartphone applications and is among the most favored for edge device and internet of things development.
- 3. James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. The small team of sun engineers called Green Team. Originally designed for small, embedded systems in electronic appliances like set-top boxes. Firstly, it was called "Greentalk" by James Gosling and file extension was .gt. After that, it was called Oak and was developed as a part of the Green project.
- 4. Object Oriented Compiled and Interpreted Language Simple Platform Independent Architectural Neutral Dynamic and Extensible Object Oriented
- 5. • Portable • Multi Threading • Distributed • Networked • More Secure Any Robust • Secured • High Performance
- 6. class keyword is used to declare a class in java. Object − Objects have states and behaviors. Example: A dog has states - color, name, breed as well as behavior such as wagging their tail, barking, eating. An object is an instance of a class. static is a keyword, if we declare any method as static, it is known as static method.
- 7. void is the return type of the method, it means it doesn't return any value. main represents startup of the program. String[] args is used for command line argument. We will learn it later. System.out.println() is used print statement. We will learn about the internal working of System.out.println statement later.
