Example 1

The following example shows the usage of Java File mkdirs() method. We've created a File reference. Then we're creating a File Object using a directory path which is not present in the given location. Using mkdir() method, we're trying to create the folder and getting the result in boolean variable. Then we're printing the status of directory being created or not.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      boolean bool = false;      
      try {
         f = new File("F:/Test2/TutorialsPoint/Java");
         
         // create the directories
         bool = f.mkdirs();
         
         // print
         System.out.print("Directory created? "+bool);
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result − assuming that we're having a test.txt file at the current location and is not writable.

Directory created? true

Now, you can check that directory structure is created.

Example 2

The following example shows the usage of Java File mkdir() method. We've created a File reference. Then we're creating a File Object using a directory path which is already present in the given location. Using mkdir() method, we're trying to create the folder and getting the result in boolean variable. Then we're printing the status of directory being created or not.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      boolean bool = false;      
      try {
         f = new File("F:/Test2/TutorialsPoint/Java");
         
         // create the directories
         bool = f.mkdirs();
         
         // print
         System.out.print("Directory created? "+bool);
         
      } catch(Exception e) {
         // if any error occurs
         e.printStackTrace();
      }
   }
}

Output

Let us compile and run the above program, this will produce the following result − assuming that we're having a test.txt file at the current location and is not writable.
