计算JAVA源代码（src）行数，不计算空行 import java.io.BufferedReader; import java.io.File; import java.io.FileReader;

private static int rand(int lo, int hi){ java.util.Random rn = new java.util.Random(); int n = hi - lo + 1;

import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException;

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class

这种类似与选择排序算法，首先我们取i值，然后将i之后的所有重复的去掉。具体实现如下： import java.util.List; import java.util.concurrent.CopyOnWriteArrayList;

/** * 读取配置文件 * @param file * @return */ public static PropertiesConfiguration loadConfig(String file){ PropertiesConfiguration config = null; try { config = new PropertiesConfiguration(file); config.s

Java.nio.channels.Pipe 提供一种机制，可以按照写入的顺序读取数据。 Pipe.SinkChannel用来向管道写入数据，而Pipe.SourceChannel用来从管道读取数据：

，每4个为一组，然后通过模62操作，结果作为索引取出字符， 这样重复率大大降低。 [Java]代码 public static String[] chars = new String[] {
