public class CanReadFileFilter extends AbstractFileFilter implements Serializable
File
s 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]); }
