>之后它只是挂起它试图通过OutputStreamWriter发送“exit\n”字符串但没有运气java的代码如下
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
try
{
int exitVal;
char c;
String ch="exit\n";
Process process = Runtime.getRuntime().exec("cmd.exe");
//"cmd /c C:/hello.exe",}
OutputStream stdin = process.getOutputStream ();
InputStream stderr = process.getErrorStream ();
InputStream stdout = process.getInputStream ();
BufferedReader reader = new BufferedReader (new InputStreamReader(stdout));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(stdin));
System.out.println("sucesss");
do{ c=(char)reader.read();
System.out.print(c);
}while(c!='>');
writer.write(ch);
exitVal=process.waitFor();
System.out.println("Exited with error code "+exitVal);
}catch (Exception e)
{
e.printStackTrace();
}
}
}
谢谢
