ZIP

Compression & Decompression in Java

Learn how Java handles data compression efficiently using java.util.zip. Explore common formats like GZIP and ZIP, understand the Deflater and Inflater classes, and see how to optimize speed vs. compression ratio for files and streams.

Core APIs

Java’s java.util.zip package supports GZIP and ZIP compression streams. DeflaterOutputStream compresses data, while InflaterInputStream restores it.

Use Cases

Ideal for compressing network payloads, logs, or archived backups. Compression minimizes storage and speeds up transmission.

Best Practices

• Use streaming APIs to handle large data.
• Test different algorithms for optimal balance.
• Avoid compressing already compressed data.

Tradeoffs

Higher compression ratios demand more CPU time. GZIP is slower but smaller, while LZ4 or Zstd (via libraries) are faster but larger.
