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.
