哪些问题阻止Java应用程序在多个平台上运行？ [英] What Issues prevent Java applications from working on multiple platforms?

问题描述

Java应该是一次编写，随处运行，它确实可以，但在某些情况下，它会变成一次编写，随处调试。

Java is supposed to be "write once, run anywhere" and it really can be, but in some cases it turns into "write once, debug everywhere".

推荐答案

• 不要假设文件系统的情况（in）灵敏度


• 不要对路径或目录分隔符做出假设


• 不要对行终止符做出假设


• 不要使用默认平台编码，除非你真的，非常确定你的意思


• 不要启动cmd.exe等（我知道，这听起来很明显 - 但我看到它的原因问题）


• Don't make assumptions about the case (in)sensitivity of the file system
• Don't make assumptions about the path or directory separator
• Don't make assumptions about the line terminator
• Don't use the default platform encoding unless you're really, really sure you mean to
• Don't start "cmd.exe" etc (I know, it sounds obvious - but I've seen it cause problems)
