Questions and Answers
What is the primary purpose of the problem definition stage in the programming cycle?
The primary purpose is to specify what we want the computer to do.
How does the problem analysis stage contribute to the programming cycle?
It breaks down the problem into smaller sub-problems for better manageability.

Study Notes
Programming Basics
- A program consists of instructions that dictate computer behavior and actions.
- A programmer is an individual involved in the creation, development, and coding of programs.
Stages of the Programming Cycle
- Problem Definition: Clearly specifies the objectives for the computer's tasks.
- Problem Analysis: Involves breaking down the main problem into smaller, manageable sub-problems.
-
Algorithm Development: Formulates strategies for task execution. Can be represented through:
- Human language (narrative algorithms)
- Graphical representation (flowcharts)
- Pseudocode
- Coding and Debugging: Involves writing the actual code and systematically removing errors from programs.
Programming Language
- Defined as a formal language that instructs computers on how to operate.
- Java is notable as a high-level, modern programming language.
Java Overview
- Designed by Sun Microsystems, with its first version released on May 23, 1995.
- Acquired by Oracle Corporation on January 27, 2010.
- Over 3 billion devices run Java applications, exemplifying its widespread use.
- Java's hallmark feature is its principle of "Write Once, Run Anywhere," ensuring compatibility across different systems.
