Java Operators & Control Flow Tutorial — Learn Operators & Control Flow in Java

Java Tutorial: Operators & Control Flow

Comparison operators, logical operators, if/else, switch expressions, and the ternary operator.

Make decisions

Every program needs to choose. `if/else` is the classic. Java's modern `switch` expressions (Java 14+) bring a cleaner syntax. And `instanceof` with pattern matching makes type checks elegant.

What you'll learn in this Java operators & control flow tutorial

This interactive Java tutorial has 7 hands-on exercises. Estimated time: 18 minutes.

if / else if / else — Java's `if/else` should feel familiar. One rule: use braces `{}` always — missing braces are a historic source of critic…
Logical operators: &&, ||, ! — Combine boolean conditions:
Ternary — one-line if/else — The ternary operator returns a value based on a condition:
switch — classic and modern — Classic switch matches exact values. Modern `switch` expression (Java 14+) uses `->` arrows and returns values — no `bre…
switch with yield — For multi-statement switch cases, use `yield` to return a value:
instanceof and pattern matching — Classic `instanceof` checks type. Java 16+ adds pattern matching — it assigns AND checks in one step:
Build a calculator — Final challenge — no starter code.
