public class CanReadFileFilter
extends AbstractFileFilter
implements java.io.Serializable

This filter accepts Files that can be read.

Example, showing how to print out a list of the current directory's readable files:

Using Classic IO

 File dir = new File(".");
 String[] files = dir.list(CanReadFileFilter.CAN_READ);
 for (String file : files) {
     System.out.println(file);
 }

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 (String file : files) {
     System.out.println(file);
 }

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 (String file : files) {
     System.out.println(file);
 }
