Using reverse compile a Process object. The class type file, throw an exception-CodePudding

Using reverse compile a Process object. The class type file, Process throws an exception:
//run the operating system command, and then sends the output to the console,

 package IO; 
import java.io.*; 

Public class OSExecute {
Public static void command (String command) {
Boolean err=false; 
Try {
//according to the incoming command sequence, to create a process 
Process Process=new ProcessBuilder (command. The split (" ")). The start (); 
//get the process output stream 
BufferedReader results=new BufferedReader (
New InputStreamReader (process. GetInputStream ())); 
String s; 
While ((s=the readLine ())!=null) 
System.out.println(s); 
//get the process error stream 
BufferedReader errors=new BufferedReader (
New InputStreamReader (process. GetErrorStream (), "GBK")); 
//if there is a problem, report the error and will be a non-zero value is returned to the calling process: 
While ((s=errors. ReadLine ())!=null) {
System. Err. Println (s); 
err=true; 
} 
} the catch (Exception e) {
//if it is a Windows 2000, it throws the default command line abnormality: 
if(! Command. The startsWith (" CMD/C ")) 
The command (+ command "CMD/C"); 
The else 
Throw new RuntimeException (e); 
} 
//if the process itself an error in the process of execution, a runtime exception is thrown separate custom 
If (err) 
Throw new OSExecuteException (" Errors executing "+ command). 
} 
} 

Package IO; 

Public class OSExecuteDemo {

Public static void main (String [] args) {
//decompiled OSExecuteDemo 
OSExecute.com mand (" javap/bin/IO/OSExecuteDemo "); 
} 

}

Run the program, the results are as follows:
Compiled from "OSExecuteDemo. Java
"Public class IO. OSExecuteDemo {
Public IO. OSExecuteDemo ();
Public static void main (Java. Lang. String []);
}
warning: binary files/bin/IO/OSExecuteDemo contains IO OSExecuteDemo
The Exception in the thread "main" IO. OSExecuteException: Errors executing javap/bin/IO/OSExecuteDemo
Mand at io.OSExecute.com (OSExecute. Java: 34)
The at IO. OSExecuteDemo. Main (OSExecuteDemo. Java: 6)

Decompiling command execution is normal, but always throw an exception, what reason is this excuse me? How to solve?
