Java History and Key Milestones: From Oak to Modern SE

Posted by on Nov 16, 2025 in Software Engineering | 0 comments

The history of Java began in 1991 at Sun Microsystems, created by James Gosling and his team. Originally intended for interactive television and consumer electronic devices, the language’s development quickly shifted to the burgeoning World Wide Web due to its platform-independent design.

Here is a breakdown of Java’s history and key milestones:

Software Testing Fundamentals and Lifecycle

Testing is Not a Single Phase in SDLC

Testing is a continuous process in the Software Development Life Cycle (SDLC), occurring in multiple stages:

  1. Requirement & Design: Reviews and validations.
  2. Development: Unit testing and code reviews.
  3. Testing Phase: Functional, system, integration, and performance testing.
  4. Deployment & Maintenance: Regression testing and monitoring.

Comment: Testing is not just a single phase but an ongoing process, ensuring software

Software Maintenance and Evolution

Four Types of Software Maintenance

There are four primary types of software maintenance:

  • Corrective: Focuses on fixing errors or bugs in the software (e.g., patching a login failure).
  • Adaptive: Involves updating the software to accommodate changes in the environment (e.g., upgrading compatibility for a new operating system).
  • Perfective: Enhances the system’s performance or user experience (e.g., optimizing database queries for faster results).
  • Preventive: Aims to prevent

Software Project Estimation and Decomposition

Decomposition Techniques in Estimation

Software project estimation is similar to problem solving. When the problem to be solved is too complex in software engineering, we decompose the given problem into a set of smaller problems.

The decomposition can be done using two approaches:

  • Decomposition of the problem (e.g., breaking down features).
  • Decomposition of the process (e.g., breaking down tasks).

Estimation uses one or both forms of decomposition (partitioning)
