recursively set 777 permissions in java without using NIO

Question

Is there a way to set 777 permissions on a path recursively(so that all directories on the path get 777 permissions) without using NIO.

We can do it for the last leaf of a given file by methods in the file class like below

import java.io.File;
import java.nio.file.FileSystems;


public class permissionTest {

    public static void main(String [] args){
        String dir = "./leaf1/leaf2/leaf3";

        File baseDir = new File(dir);

        boolean success = baseDir.mkdirs();
        if (success) {
            System.out.println("Created dirs");
            baseDir.setExecutable(true, false);
            baseDir.setReadable(true, false);
            baseDir.setWritable(true, false);
        }
        else{
            System.out.println("Not created");
        }

    }

}

the above gives 777 to leaf3 , how to give 777 to leaf1 & leaf2 as well? In a single command?

Answer 1

Process p;
        try {
            p = Runtime.getRuntime().exec("chmod 777 -R ./leaf1");
            p.waitFor();

        } catch (Exception e) {
            e.printStackTrace();
        }
