Optimizing for SpeedThe programming community seems to believe that choosing Java as a language inevitably means poor performance. In reality, as you might expect, the speed of a Java application depends very much on the quality of the code. Indeed, improvements in performance from good coding can far outweigh those achieved from using a faster virtual machine.红润 发表于 2025-3-24 17:50:35

Persistent Storage of Objectsyou read the file, which meant that you had to indicate that certain data were associated with certain objects and that certain objects were related. This was a very time-consuming and error-prone task. Also, unless you used existing file formats, it was unlikely that your data could be used by other applications.CLAP 发表于 2025-3-25 02:36:34
