java.io.File setExecutable(boolean executable)

Description

On this document we will be showing a java example on how to use the setExecutable(boolean executable) method of File┬áClass. This method┬áis a convenience┬ámethod to set the owner’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.

An invocation of this method of the form file.setExcutable(arg) behaves in exactly the same way as the invocation

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)

Method Argument

Data Type Parameter Description
boolean executable If true, sets the access permission to allow execute operations; if false to disallow execute operations

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
