Returns an array of strings naming the files and directories in the directory denoted by this abstract pathname that satisfy the specified filter.

Usage

From source file:Main.java

public static void main(String[] args) {
    final String dir = "C:\\data\\projects\\";
    final String pattern = ".pdf";
    final File file = Paths.get(dir).toFile();

    Stream.of(file.list((pFile, pString) -> pString.endsWith(pattern))).forEach(System.out::println);
    ;/*w ww  .j a v a 2 s  . c  o  m*/
}

From source file:DirListOnly.java

public static void main(String args[]) {
    String dirname = "/java";
    File f1 = new File(dirname);
    FilenameFilter only = new OnlyExt("html");
    String s[] = f1.list(only);

    for (int i = 0; i < s.length; i++) {
        System.out.println(s[i]);
    }//  w ww .  j a  v a  2s. co m
}
