How to open an exe file in java
提问by user2947797
I am trying to use java to open an exe file. I'm not sure which program I want to open so I am using Skype as an example. When I try to do it, it gives me errors.
我正在尝试使用 java 打开一个 exe 文件。我不确定要打开哪个程序，所以我以 Skype 为例。当我尝试这样做时，它给了我错误。
try {
Process p = Runtime.getRuntime().exec("C:\Program Files (x86)\Skype\Phone\Skype");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
error: Cannot run program "C:\Program": CreateProcess error=2, The system cannot find the file specified

You are on windows so you have to include the extension .exe
您在 Windows 上，因此必须包含扩展名 .exe
try {
Process p = Runtime.getRuntime().exec("C:/Program Files (x86)/Skype/Phone/Skype.exe");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Maybe use File.separatorinstead of '\'
也许使用File.separator而不是 '\'

You have to use a string array, change to
您必须使用字符串数组，更改为
try {
Process p = Runtime.getRuntime().exec(new String[] {"C:\Program Files (x86)\Notepad++\notepad++.exe"});
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Try this:
尝试这个：
String path = "/path/to/my_app.exe";
File file = new File(path);
if (! file.exists()) {
throw new IllegalArgumentException("The file " + path + " does not exist");
}
Process p = Runtime.getRuntime().exec(file.getAbsolutePath());

I tried this and it works fine, it's taken from your example. Pay attention to the double \\
我试过这个，它工作正常，它取自你的例子。注意双\\
public static void main(String[] args) {
try {
Process p;
p = Runtime.getRuntime().exec("C:\Program Files\Java\jdk1.8.0_05\bin\Jconsole.exe");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
