Files that can be read.
Example, showing how to print out a list of the current directory's readable files:
File dir = new File(".");
String[] files = dir.list( CanReadFileFilter.CAN_READ );
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-readable files:
File dir = new File(".");
String[] files = dir.list( CanReadFileFilter.CANNOT_READ );
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 read-only files:
File dir = new File(".");
String[] files = dir.list( CanReadFileFilter.READ_ONLY );
for ( int i = 0; i < files.length; i++ ) {
System.out.println(files[i]);
