How to invoke a shell script file in Java

Source:

Public StaticString CreateFile () {String cmd ="Echo\"Hhahah\"> F:\\AAA\\Azzz.txt "; File File =NewFile ("C:\\Windows\\System32 "); StringBuilder result =NewStringBuilder ();Try{//execute the specified string command in a separate process processes process = Runtime.getruntime (). exec (CMD);intExecresult = Process.waitfor (); System. out. println ("Execution results:"+execresult); BufferedReader input =NewBufferedReader (NewInputStreamReader (Process.getinputstream ())); String line =""; while(line = Input.readline ())!=NULL) {System. out. println (line);
        Result.append (line);
    } input.close (); }Catch(IOException e)
    {E.printstacktrace (); }Catch(Interruptedexception e)
    {E.printstacktrace (); } System. out. println ("The string result is:"+result); return""; }Public static voidMain (string[] args) {CreateFile ();}

The original program, such as on, run when the error message is as follows:

Description, when invoking the cmd command in Java, you need to specify

That is, the command that is invoked needs to indicate whether CMD is running the command

Modify:

\" Hhahah \" > F: \\ AAA \\ azzz.txt ";

Indicate:

The Runtime.exec method creates a native process and returns an instance of the process subclass that can be used to control the process and obtain relevant information
