public class CanWriteFileFilter extends AbstractFileFilter implements Serializable
Files that can be written to.
Example, showing how to print out a list of the current directory's writable files:
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.
