---

---

.

Description

The Java File setExecutable(boolean executable, boolean ownerOnly) method to set the owner's or everybody's execute permission for this abstract pathname.

Declaration

Following is the declaration for java.io.File.setExecutable(boolean executable, boolean ownerOnly) method −

public boolean setExecutable(boolean executable, boolean ownerOnly)

Parameters

• executable − true sets the access permission to allow execute operations, false denies execute operation.

• ownerOnly − true sets the execute permission only to the owner's execute permission; otherwise, it applies to everybody.

Return Value

This method returns true if the operation succeeded, else false.

Exception

SecurityException − If a security manager exists and its method denies write access to either the old or new pathnames.

Example 1

The following example shows the usage of Java File setExecutable() method. We've created a File reference. Then we're creating a File Object using a file path which is present in the given location. Using setExecutable() method, we're trying to make the file excutable and getting the result in boolean variable. Then we're printing the status of file as executable using canExecute() method and result is printed.

import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      boolean bool = false;      
      try {     
      
         // create new File objects
         f = new File("F:/test.txt");
         
         // set executable as true for owner
         bool = f.setExecutable(true, true);
         
         // prints
         System.out.println("setExecutable() succeeded?: "+bool);
         
         // can execute
         bool = f.canExecute();
         
         // prints
         System.out.print("Can execute?: "+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 −

setExecutable() succeeded?: true
Can execute?: true

Example 2

The following example shows the usage of Java File setExecutable() method. We've created a File reference. Then we're creating a File Object using a file path which is present in the given location and was made executable in previous example. Using setExecutable() method, we're trying to make the file non-executable and getting the result in boolean variable. Then we're printing the status of file as executable using canExecute() method and result is printed.

package com.tutorialspoint;
import java.io.File;
public class FileDemo {
   public static void main(String[] args) {      
      File f = null;
      boolean bool = false;      
      try {     
      
         // create new File objects
         f = new File("F:/test.txt");
         
         // set executable as true for all
         bool = f.setExecutable(true, false);
         
         // prints
         System.out.println("setExecutable() succeeded?: "+bool);
         
         // can execute
         bool = f.canExecute();
         
         // prints
         System.out.print("Can execute?: "+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 −

setExecutable() succeeded?: true
Can execute?: true
