Study Notes

Programming Concepts

Operators in programming include && (and), || (or), > (greater than), and = (equal).
High-level programming languages are largely independent of any specific computer type and closer to human language.
Object-oriented programming focuses on data structures as objects, establishing relationships between them through classes.

Current and Distributed Programming

Concurrent programming allows multiple operations to execute simultaneously, sharing resources.
Parallel processing runs processes side by side while remaining independent.
Grace Hopper developed the first compiler in the early 1950s, coining the term "compiler".

Generations of Programming Languages

First Generation (Machine Language): Utilizes binary code (0s and 1s), is machine-dependent, and is a low-level language.
Second Generation (Assembly Language): Uses mnemonics for commands and must be converted by an assembler, remaining a low-level language.
Third Generation (High-Level Language): More independent from computer type, closer to human languages, emphasizes ease of reading, writing, and maintenance, and includes languages like FORTRAN, BASIC, and C++.

Types of Programming Errors

Syntax Errors: Arise from incorrect syntax of the programming language.
Semantic Errors: Occur from improper use of statements in the program.
Logical Errors: Happen when specifications are not respected.
Compile Time Errors: Emerge before running the program due to syntax or type-related issues.
Runtime Errors: Occur during execution due to unforeseen situations, such as dividing by zero.

Java Programming Language

Developed by James Gosling and team in 1991, initially envisioned for interactive television, originally called OAK.
Released by Sun Microsystems in 1995, featuring a "Write Once, Run Anywhere" philosophy.
Java, influenced by C and C++, uses classes, methods, and objects for application development.
Acquired by Oracle in 2009, with James Gosling leaving Oracle in 2010.

Java Applications

Java Applets: Programs downloaded from the internet, executed in a web browser.
Applications: Standalone programs running on local computers.
Java Archive (JAR): Package format aggregating Java class files and resources.
Servlets: Server-side components managing requests and responses in web applications.
Swing Applications: Desktop applications utilizing the Swing toolkit for GUIs.
Enterprise Java Beans (EJB): Encapsulate business logic for enterprise applications.

Characteristics and Benefits of Java

Java is simple, object-oriented, distributed, interpreted, and robust.
Offers platform independence and high performance due to the Java Virtual Machine (JVM).
Ensures variables must be initialized before use, reducing errors from uninitialized variables.
Guarantees methods that return values adhere to predictable behavior.
Extensive API provides pre-built classes and methods for enhanced programming efficiency.
Maintains consistent bit size, despite being slower than C due to JVM overhead.
