Study Notes
COMPUTER PROGRAMMING
- Computer programming involves writing instructions, termed source code, for computer systems.
- Binary code, consisting of 1's and 0's, is the fundamental language understood by computers.
PROGRAMMING LANGUAGE TYPES
-
Low-level Programming Language: Closely aligned with machine instructions, interacting directly with hardware.
- Divided into:
- Machine Language: Represented in binary code, the basic language of computers.
- Assembly Language: Utilizes mnemonics for hardware communication, serving as an intermediary between high-level languages and machine code.
- Divided into:
-
High-level Programming Language: Easier for humans to read and write. Includes symbols and phrases that simplify logic representation.
- Examples: FORTRAN, C, C++, Java, Python.
TRANSLATORS
- Essential for transforming source code into machine language (binary form).
- Types include:
- Assemblers: Converts assembly language into machine code.
- Compilers: Translates source code into binary code, executing it afterward. Notable compiled languages: C, C++, Swift.
- Interpreters: Converts and executes code line by line, halting upon error. Popular interpreted languages: Python, Ruby, JavaScript.
- Hybrid Translators: Combine features of compilers and interpreters, such as the Java Virtual Machine (JVM).
JAVA PROGRAMMING
- Initiated by James Gosling in the early 1990s to develop software for digital devices.
- Originally called “Greentalk,” then renamed “OAK,” inspired by an oak tree near Gosling’s office.
- Java applications require the Java Runtime Environment (JRE), Java Development Kit (JDK), and JVM for execution and development.
PROGRAM DEVELOPMENT PROCESS
- Includes writing code, compiling it to bytecode, and running the compiled code via JVM.
- Programming phases:
- Write code
- Compile with a Java compiler
- Run using JVM
ERRORS AND DEBUGGING
- Syntax errors identified during compilation; logical errors often discovered during program output.
- Debugging involves correcting syntax and ensuring logical accuracy.
INTEGRATED DEVELOPMENT ENVIRONMENT (IDE)
- Software tools for writing, running, and debugging code, as well as converting it to machine code.
- Examples: NetBeans, Eclipse, IntelliJ, Visual Studio.
ALGORITHM, PSEUDOCODE & FLOWCHART
- Algorithm: Step-by-step instructions for performing a task.
- Pseudocode: Informal, high-level description of algorithms.
- Flowchart: Visual representation of a process, using symbols and arrows to show the flow of steps.
EXAMPLES
- Simple programs include displaying "Hello World," adding integers, and converting kilograms to grams illustrated through algorithms, pseudocode, and flowcharts.
PERFORMANCE TASK
- Create algorithms, pseudocode, and flowcharts addressing user input for displaying name, age, and course, as well as adding three integers and calculating averages.
