## 2024-12-25 - [Java String.repeat]
**Learning:** Simple loops for string repetition can be replaced with `String.repeat` in Java 11+. This is cleaner and often more efficient as it reduces loop overhead and buffer resizing.
**Action:** Look for loop-based string repetition patterns in Java code and replace with `String.repeat`.
