# Java程序设计 vs 极客手册

The clearest difference is rating: Java程序设计 at 5.0 against 极客手册's 1.0. 极客手册's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Java程序设计 sells 1 one-off in-app purchase and 极客手册 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Java程序设计 holds the better App Store score, 5.0 against 1.0. Both are backed by a comparable volume of ratings — 2 and 2 respectively.

Java程序设计 ships an update every 3 months, 极客手册 every 3 weeks. The most recent releases landed on June 1, 2026 and September 13, 2026 respectively.
