Usage

From source file:ShowFile.java

public static void main(String args[]) throws IOException {
    int i;//  ww  w . j  a va2  s  .c om
    FileInputStream fin;

    try {
        fin = new FileInputStream(args[0]);
    } catch (FileNotFoundException e) {
        System.out.println("File Not Found");
        return;
    } catch (ArrayIndexOutOfBoundsException e) {
        System.out.println("Usage: ShowFile File");
        return;
    }
