I am trying to open a PDF file from java using the command line argument as

String command = "cmd /c start AcroRd32.exe \"" + dir + "\"";

推荐答案

我强烈建议你这样做此方式

I strongly recommend that you do it this way instead.

java.io.File file = new java.io.File("c:/some/file.pdf");
java.awt.Desktop.open(file);

如果您还想运行AcroRd32.exe（或其他命令 ProcessBuilder ，具有类似这样的内容 -

If you still want to run "AcroRd32.exe" (or some other "command") use a ProcessBuilder, with something like this -

ProcessBuilder pb = new ProcessBuilder("AcroRd32.exe", dir);
Process p = pb.start();
