On this document we will be showing a java example on how to use the setWritable(boolean writable) method of File Class. This method is a convenience method to set the owner’s write 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 modify files that disallow write operations.
An invocation of this method of the form file.setWritable(arg) behaves in exactly the same way as the invocation
SecurityException – If a security manager exists and its SecurityManager.checkWrite(java.lang.String) method denies write access to the file.
public boolean setWritable(boolean writable)
If true, sets the access permission to allow write operations; if false to disallow write operations
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.
Requires Java 1.6 and up
Java File setWritable(boolean writable) Example
Below is a java code demonstrates the use of setWritable(boolean writable) method of File class. The example presented might be simple however it shows the behaviour of this method.
