# TheAlgorithms/Java

> A collection of classic algorithms and data structures implemented in Java for educational purposes, not optimized for production use. It serves as a reference and practice ground for students and developers learning algorithms.

- Magnitude: 2.1 out of 10 — Steady
- Stars: 67,244 total · +14 stars measured 2026-11-14, 00:05–11:17 UTC, ≈ 27 by evening
- Star trust: star growth looks organic

## Useful for

- Study sorting and search algorithm implementations in Java
- Use as reference when preparing for coding interviews
- Contribute a new algorithm implementation to the repository

## Why it’s here

- Star-counter measurements on 2026-11-14 (UTC), 00:05–11:17: 67230 → 67244 stars (+14). This is the change over that interval.
- Estimated end-of-day forecast: about +27 stars, using observed gains and the previous day.
- Interest is fading: the two-day pace is 52% of the previous week and a half.
- About 7 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 21,532
- Issues and pull requests: 7,424
- Watchers: 2,165
- Average over the last week: 76 per day
- Usual pace: 18 per day
- Stars in the last hour (measured): 1

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
Data as of 2026-11-14 11:22 UTC, updated every 30 minutes.
