我的程序可以运行，并且在 Eclipse 中得到了所需的输出，但是在 Putty 上却失败了。
期望的输出是: [Eclipse 输出]
但是在腻子上我得到了这个:
因此，在每个“Command.....”文本之后应该有一些输出，然后是“------------”。但是它只打印命令文本和“--------” -”。有人知道为什么吗？我的意思是为什么它与 Eclipse 中的输出不同？
这是我的主要类(class):

最佳答案
这都是关于 javac 在编译类文件时在 putty 上工作的方式。它的全名是 Java 编程语言编译器，它的参数类型为命令:
javac [ options ] [ sourcefiles ] [ classes] [ @argfiles ]
当您将文件上传到 putty 服务器并尝试使用 javac 编译多个没有任何特定关系(继承、实现、包类依赖性等)的文件时，它会采用以下文件名:您编写了(假设您使用了javac fileName.java)并开始对其进行处理。如果它在编译时发现与另一个文件的绑定(bind)，它也会编译它。然而，在这种特定情况下( as we discussed on chat )，该程序的某些类文件与其他文件没有一定的关系，因此编译器忽略它们的边界。
因此，您应该像上面所示那样编写文件名、路径等。您还可以在 java docs 上找到更多详细信息。 。不要介意纠正我或添加一些东西，祝你有美好的一天!
