Java File setExecutable(boolean writable, boolean ownerOnly) method example 2018-02-16T07:26:40+00:00 setExecutable(boolean executable, boolean ownerOnly)


On this document we will be showing a java example on how to use the setExecutable(boolean executable, boolean ownerOnly) method of File┬áClass. This method┬ásets the owner’s or everybody’s execute permission for this abstract pathname. On some platforms it may be possible to start the Java virtual machine with special privileges that allow it to execute files that are not marked executable.

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.


  • 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.


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.
