The following Java code does the following:

1. Filters files for an array of extensions.
2. Splits file names.
3. Tests the resulting array

package FileHandling;
import java.io.File;
import java.io.FilenameFilter;
/**
* filters files for an array of extensions critstr
* splitting file name by splitstr
* last element of resulting array being tested
* @author emniyet
*/
public final class MyFileFilter implements FilenameFilter {
private String [] critstr;
private String splitstr;
public void setCriteria(String splitstr, String [] critstr) {
this.splitstr=splitstr;
this.critstr=critstr;
}
public boolean accept(File dir, String name) {
boolean res=false;
String [] string = name.split(splitstr);
Y:
for (int j=0;j<critstr.length;j++){
if(string[string.length-1].equalsIgnoreCase(critstr[j])) {
res=true;
break Y;
}
}
return res;
}
}
code fragment using the FileNameFilter.
