Java Exception Handling Tutorial: try-catch-finally, try-with-resources and Custom Exceptions

Submitted by jaypabs on

Sooner or later every Java program meets bad input, a missing file or a network that is down. If you do not plan for it, your program crashes with a long red stack trace, and in a capstone defense that usually happens at the worst possible moment. Exception handling is how Java lets you catch those problems, react to them, and keep the program running or fail with a clear message.

How to Name Variables and Functions: Clean Code Naming Tips with Python, JavaScript and PHP Examples

Submitted by jaypabs on
Ask any senior developer what makes code hard to work with, and you will hear the same answer again and again: bad names. A function called calc(), a variable called x, a column called flag2. The code runs, but nobody, including you three weeks later, can tell what it does without reading every line. Naming is a skill you can learn, and it pays off right away: in capstone defenses, in code reviews

PHP password_hash and password_verify Tutorial: Secure Registration and Login with PDO and MySQL

Submitted by jaypabs on

Almost every PHP project needs a login page: a capstone system, an inventory app, a school portal, an admin panel. And almost every beginner tutorial from ten years ago still saves passwords with md5(). That is the one part of a login system you really cannot get wrong, because if your database ever leaks, weak password hashes turn into real passwords within minutes.

SQL GROUP BY and HAVING Tutorial: COUNT, SUM, AVG, ROLLUP and Pivot Reports in MySQL

Submitted by jaypabs on

Totals, averages and counts are the heart of almost every report: sales per branch, students per course, orders per day, the best-selling product this week. In SQL, all of these come from one clause: GROUP BY. Paired with aggregate functions like COUNT, SUM and AVG, and filtered with HAVING, it turns thousands of rows into a short summary you can show on a dashboard.

SQL injection is one of the oldest web security bugs, and it still shows up in student projects, freelance work and even production apps.

Python JSON Tutorial: dumps, loads, dump, load, Pretty Print and Error Handling

Submitted by jaypabs on

JSON is everywhere in modern programming. REST APIs send it, JavaScript front ends expect it, configuration files are written in it, and many capstone projects store small amounts of data in a .json file before they move to a real database. If you write Python, sooner or later you will need to turn a dictionary into JSON or read a JSON response back into Python.
