悬赏公告图片:有人了解java-Textpad吗？

java-Textpad是用来编写java程序的，并且能直接运行感觉还好，但是有个问题很令人烦恼，就是刚编写的程序保存路径都正确，运行也很成功．当我过了一会儿以相同的方法重新运行它的时候，因错误而不能运行，错误提示是：javac: invalid flag: C:\j2sdk1.4.2_02\bin\A.java.txt
Usage: javac <options> <source files>
where possible options include:
-g Generate all debugging info
-g:none Generate no debugging info
-g:{lines,vars,source} Generate only some debugging info
-nowarn Generate no warnings
-verbose Output messages about what the compiler is doing
-deprecation Output source locations where deprecated APIs are used
