Study Notes
- Java is a simple programming language with a list of important features, including being object-oriented, portable, platform-independent, secure, robust, and distributed.
- Java syntax is based on C and is easy to learn.
- Java removes complicated and rarely used features, such as explicit pointers and operator overloading, and uses automatic garbage collection.
- Java is object-oriented, meaning everything is an object, and it uses inheritance, polymorphism, abstraction, and encapsulation.
- Java is platform-independent and is a write-once, run-anywhere language. It uses a software-based platform with a runtime environment and an application programming interface.
- Java is secured with no explicit pointers and Java programs run inside a virtual machine sandbox with a classloader and a Security Manager.
- Java is robust with strong memory management, automatic garbage collection, exception handling, and type checking.
- Java is architecture neutral, meaning there are no implementation dependent features.
- Java is portable, facilitating the carrying of Java bytecode to any platform.
- Java is faster than other traditional interpreted programming languages due to the Java bytecode being close to native code.
- Java is distributed, allowing for the creation of distributed applications and accessing files from any machine on the Internet.
- Java supports multi-threading, allowing for the writing of Java programs that can deal with many tasks at once without occupying separate memories.
- Java is a dynamic language that supports dynamic loading of classes, and functions from its native language C and C++.
- Java supports dynamic compilation and automatic memory management with garbage collection.
