This filter accepts
File
s that can be written to.
Example, showing how to print out a list of the current directory's writable files:
Using Classic IO
File dir = new File("."); String[] files = dir.list(CanWriteFileFilter.CAN_WRITE); for (String file : files) { System.out.println(file); }
Example, showing how to print out a list of the current directory's un-writable files:
File dir = new File("."); String[] files = dir.list(CanWriteFileFilter.CANNOT_WRITE); for (String file : files) { System.out.println(file); }
N.B. For read-only files, use CanReadFileFilter.READ_ONLY
