convert a string to a directory name

Question

Here is my case:

String dir = "C:/root/dir1/";
for(File f: new File(dir).listFiles()) {

}

On executing:

System.out.println(new File(dir).isDirectory());
System.out.println(new File(dir));

gives

false
root/dir1

The path stored in the string is valid. On converting the string to file type it looses the separator; how can the directory name be preserved?

Thank you.

Solution

To create a directory use the following code. Note the use of .mkdir() method and the double backslash.

In your code I would bet System.out.println(new File(dir).isFile() would return true.

 import java.io.File;

 public class MakeDirectory {

 public static void main(String[] args) {
    File f = new File("c:\\MyFolder");
    f.mkdir();

  }
 }
