File yourFolder = new File("/home/emschwar");
for (String n : yourFolder.list()) {
    System.out.println("directory entry named [" + n + "]");
}

/// shorter:

for (String n : new File("/home/emschwar").list()) {
    System.out.println("directory entry named [" + n + "]");
}

/// shorter:
    /// using jakarta-commons-IO + Java 5 static-imports
    /// I'm always using jakarta-commons

for (String n : list("/home/emschwar")) {
    out.println("directory entry named [" + n + "]");
}
