How to execute dir dos command in Runtime Execution

Question

Hi All,
Does anybody know how to execute the dir command in DOS in the runtime execution
for example,
when we open the command prompt,
c:\Documents and Settings\java> e:
e:\cd java
e:\dir *.*
how we can list the directory in runtime execution?

Answer 1

Process childProcess = Runtime.getRuntime().exec("cmd /C dir *.*");or try with
ProcessBuilder pb = new ProcessBuilder("cmd /C dir *.*");
Process childProcess = pb.start();
NOTE: We can use the ProcessBuilder class from J2SE 5.0+.
for further reference check the below link

and don't forget to go through API documentation for java.lang package
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/package-summary.html
and if you want to implement it through Java which provides you a list of Files & directories in the present directory here is an example of such code snippet REF:as insisted by my fellow poster.
File file = new File("<present_directory_path>");
if(file.isDirectory()){
   String fileNames[] = file.list();
        for(String fileName:fileNames)
           System.out.println(fileName);
  fileNames = null;
        or for detailed info use
         File files[] = file.listFiles();
         for(File fileEntity:files)
            System.out.println("FILENAME:"+fileEntity.getName+",IS FOLDER:"+fileEntity.isFolder()+",ABSOLUTE PATH:"+fileEntity.toString()+"FILE SIZE:"+fileEntity.length());
         files = null;
}and please do not forget to go through File API Documentation provided as recommended by my fellow poster.
hope this might help :)
