A new DEV Community post walks through three foundational Java programs for beginners. The examples demonstrate core control flow statements: a switch statement mapping numbers to days of the week, an if-else ladder for checking vowels, and a conditional chain for a simple traffic light simulator. Each program includes sample input and output.

These exercises target fundamental programming concepts rather than advanced features. The switch example handles integer input for day mapping, while the vowel checker uses character comparisons. The traffic light program uses string equality checks. This approach helps new developers practice logic flow and basic syntax without complex dependencies.

For learners, these snippets provide a practical starting point for building interactive console applications. Mastering these control structures is essential before tackling object-oriented design or external libraries. The post serves as a scaffold for understanding how programs process input and make decisions, a core skill for any developer's toolkit.
