countlines.java

主要通过JAVA 来实现声音的处理

import java.io.*;

public class CountLines {
    public static void main(String[] arguments) {
        int count = 0;
        String verbose = System.getProperty("display.verbose");
        try {
            FileReader file = new FileReader(arguments[0]);
            BufferedReader buff = new BufferedReader(file);
            boolean eof = false;
            while (!eof) {
                String line = buff.readLine();
                if (line == null)
                   eof = true;
                else {
                   count++;
                   if (verbose != null)
                       if (verbose.equals("true"))
                           System.out.println(line);
                }
            }
            buff.close();
            System.out.println(arguments[0] + " contains " + count
                + " lines");
        } catch (IOException e) {
            System.out.println("Error -- " + e.toString());
        }
    }
}
