Why Bad Code Persists: 3 Core Reasons and How to Fix It

1. Reasons

The author reflects on why the industry constantly generates poor code, noting that truly high‑quality developers are rare while many fall somewhere in between, and that the problem is not merely about salary or incentives.

2. Low Expectations

Many beginners learn programming from self‑study or textbooks that do not reflect real‑world development needs, leading to the belief that only extensive experience can produce good code. Leaders often set low standards for newcomers, allowing low‑quality developers to flood the market, which hurts those who care about craftsmanship.

3. Programming Books

Early programming books, especially those for Java beginners or certification, frequently contain bad examples. Influential authors like Robert Martin have shown many error‑prone snippets in “Clean Code” and “Practical Programming,” reinforcing poor habits among novices.

Typical bad patterns include poorly named classes, variables, and methods; lack of separation of concerns with massive main() functions; and bad coding practices such as missing validation, inadequate exception handling, and overuse of large try‑catch blocks, if‑else chains, switch statements, and even goto‑style logic.

4. Shortcuts

Some books promote shortcut‑heavy styles, like methods with ten parameters or Boolean flags that force extra if‑else logic, resulting in bloated, redundant code. While learning programming, one should first master language syntax, then acquire efficient tools, and finally focus on component and module design.

Most books stay at the syntax level and ignore tooling and design improvements, leaving beginners hungry for more. Teaching code as a communication tool for other developers—not just for compilers—is essential for raising overall code quality.

Ultimately, learning to write high‑quality code should be part of every programming book, not just expert‑level texts.
