Readability Pitfalls

Keep expressions clear.

Power Can Hurt Readability

Ternaries are concise, but overusing them can make code cryptic.

The goal is clarity, not the fewest characters. A line a reader cannot parse at a glance is a bug waiting to happen.

This lesson covers common pitfalls and how to avoid them.

Stacking many ternaries on one line is hard to read and easy to get wrong.

Each extra level multiplies the mental effort needed to trace the logic.

// hard to follow on one line
String g = s>=90?"A":s>=80?"B":s>=70?"C":s>=60?"D":"F";
