Study Notes
Key Features of Java Programming Language
- Java Standard Edition (Java SE) provides a foundation for building and deploying network-centric enterprise applications.
- Java Enterprise Edition (Java EE) is used for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.
- Java Micro Edition (Java ME) is a flexible environment for applications running on embedded and mobile devices.
- Java inherits the C/C++ syntax and many of the object-oriented features of C++, making it easy to learn for C/C++ programmers.
- Java provides automatic garbage collection, simplifying the task of memory management for programmers.
- Java programs compile into bytecode, which runs on the Java virtual machine (JVM), making it an architecture-neutral language.
- Java bytecode is interpreted on the fly and not stored anywhere, making development more rapid and exploratory.
- Java's security manager runs dynamic content under the sandbox model, improving security.
- Java uses a formal object-oriented programming (OOP) type system, helpful for keeping large projects consistent.
- Java is a strongly typed language, allowing for extensive compile-time checking and early bug detection.
- Java's garbage collector manages memory, avoiding memory leaks due to mismanagement.
- Java supports multithreaded programming, allowing for programs that do many things simultaneously.

Key Features of Java: Object-Oriented, Robust, and Secure
- Java Standard Edition (Java SE) is a foundation for building and deploying network-centric enterprise applications, implemented by the Java Software Development Kit (SDK).
- Java Enterprise Edition (Java EE) is used for developing and running large-scale, multi-tiered, scalable, reliable, and secure network applications.
- Java Micro Edition (Java ME) provides a flexible environment for applications running on embedded and mobile devices, which are portable across many devices.
- Java inherits the C/C++ syntax and object-oriented features of C++, but simplifies the task of a programmer with automatic garbage collection.
- Java bytecode is an intermediate set of instructions that are executed by a Java runtime system, known as JVM, making Java an architecture-neutral language that works on the concept of Write Once Run Anywhere.
- Java bytecode is interpreted on the fly to native machine instructions, making development more rapid and exploratory.
- Java has a security manager responsible for the security policy of Java, running dynamic content under the sandbox model, and performing various run-time checks to improve security.
- Java provides a formal OOP type system that must be obeyed at compile-time and run-time, helpful for larger projects.
- Java is strongly typed, allowing extensive compile-time checking, garbage collection to manage memory, and exception handling to make programs more robust.
- Java supports multithreaded programming, allowing programs to do many things simultaneously.
- JDK is used for developing and running Java code, while JRE is used for running Java code.
- Both JVM and JRE contain the JVM.
