public class CanWriteFileFilter extends AbstractFileFilter implements java.io.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 ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
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 ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
}
N.B. For read-only files, use
CanReadFileFilter.READ_ONLY.
