java.io.File setExecutable(boolean executable, boolean ownerOnly)
Description
The Files class defines methods that operate on file attributes including file permissions. This may be used when finer manipulation of file permissions is required.
Throws:
- SecurityException – If a security manager exists and its SecurityManager.checkWrite(java.lang.String) method denies write access to the file.
Method Syntax
public boolean setExecutable(boolean executable, boolean ownerOnly)
Method Argument
Data Type | Parameter | Description |
---|---|---|
boolean | executable | If true, sets the access permission to allow execute operations; if false to disallow execute operations |
boolean | ownerOnly | If true, the execute permission applies only to the owner’s execute permission; otherwise, it applies to everybody. If the underlying file system can not distinguish the owner’s execute permission from that of others, then the permission will apply to everybody, regardless of this value. |
Method Returns
This method returns boolean, true if and only if the operation succeeded. The operation will fail if the user does not have permission to change the access permissions of this abstract pathname. If executable is false and the underlying file system does not implement an execute permission, then the operation will fail.
Compatibility
Requires Java 1.6 and up
Java File setExecutable(boolean executable, boolean ownerOnly) Example
Below is a java code demonstrates the use of setExecutable(boolean executable, boolean ownerOnly) method of File class. The example presented might be simple however it shows the behaviour of the setExecutable(boolean executable, boolean ownerOnly) method of File class.
Basically we basically set a file as executable and we put a check if the operation succeeded or not.
package com.javatutorialhq.java.examples; import java.io.File; /* * This example source code demonstrates the use of * setExecutable(boolean writable, boolean ownerOnly) method of File class. * */ public class FileSetExecutableExample1 { public static void main(String[] args) { // initialize File object File file = new File("C:javatutorialhqinputtest_file.txt"); // check first if file exist if(file.exists()){ // set file as executable considering if the user is the owner or not boolean result = file.setExecutable(true, false); // evaluate the result if(result){ System.out.println("Operation succeeded"); }else{ System.out.println("Operation failed"); } }else{ System.out.println("File does not exist"); } } }
