我需要在它自己的命令窗口中运行一个程序，但我不知道如何在主要操作系统中执行此操作，我知道在Windows中我可以使用启动命令但是我没有＆＃ 39;不知道start的命令等同于其他操作系统。以下代码是我到目前为止的代码：
switch(OS.THISOS){//OS has information about the current OS such as what OS it is and the locations of things like appdata, user home, and user working directory
case OS.WINDOWS :
cmd.add("/c");
cmd.add("start");
cmd.add("java");
cmd.addAll(Arrays.asList(Init.getCommand()));//this gets the jvm arguments that this program needs
new Exec().exec("cmd", cmd.toArray(new String[cmd.size()]));//because start can not be directly executed through exec, I run cmd.exe and pass start in as an argument along with the command to run my program
break;//Exec is a class that handles IO streams for the sub process
case OS.MAC :
//I believe open is the command for MAC but I don't know if it can be directly run with exec or if I need to do something similar to what I did for Windows, also if the later is the case how would I do that?
break;
case OS.LINUX :
//I have seen several answers to this one but I don't know which command works best
break;
case OS.SOLARIS :
//no idea what to do here
break;
default:
System.err.println("OS not supported");//this should never happen since the program will crash in Init if the OS is unknown
return;
}
修改 我做了一些研究并提出了这个问题，但我不知道这是否有效：
switch(OS.THISOS){
case OS.WINDOWS :
cmd.add("/c");
cmd.add("start");
cmd.add("java");
cmd.addAll(Arrays.asList(Init.getCommand()));
new Exec().exec("cmd", cmd.toArray(new String[cmd.size()]));
break;
case OS.MAC :
cmd.add("-a");
cmd.add("java");
cmd.add("--args");
cmd.addAll(Arrays.asList(Init.getCommand()));
new Exec().exec("open", cmd.toArray(new String[cmd.size()]));//will this work?
break;
case OS.UNKNOWN :
System.err.println("OS not supported");
break;
default://at this point it's Linux, Solaris, or some other Unix system, xterm is the closest I can find to what I want
cmd.add("-e");
cmd.add("java");
cmd.addAll(Arrays.asList(Init.getCommand()));
new Exec().exe("xterm", cmd.toArray(new String[cmd.size()]));
return;
}
如果我这样做有什么问题，请告诉我如何解决它。
