Operators
Everyday operators plus the ternary and instanceof pattern.
java
// Quick Reference
+ - * / % // arithmetic
== != < > <= >= // comparison
&& || ! // logical
condition ? a : b // ternary💡 Integer division drops the remainder; make one operand a double for real division.
⚡ && and || short-circuit - the right side is skipped when the result is known.
📌 instanceof pattern binds a typed variable, removing the manual cast.
🟢 Use == for primitives, but .equals() to compare object contents like Strings.
