165、编写一个程序，将a.txt文件中的单词与b.txt文件中的单词交替合并到c.txt文件中，a.txt文件中的单词用回车符分隔，b.txt文件中用回车或空格进行分隔。答：package net.cfei;import java.io.File;import java.io.FileReader;import java.io.FileWriter;
public class MainClass{public static void main(String[] args) throws Exception{FileManager a = new FileManager("a.txt",new char[]{'\n'});FileManager b = new FileManager("b.txt",new char[]{'\n',' '});FileWriter c = new FileWriter("c.txt");String aWord = null;String bWord = null;while((aWord = a.nextWord()) !=null ){c.write(aWord + "\n");bWord = b.nextWord();if(bWord != null)c.write(bWord + "\n");}while((bWord = b.nextWord()) != null){c.write(bWord + "\n");}c.close();}}
class FileManager{
String[] words = null;int pos = 0;public FileManager(String filename,char[] seperators) throws Exception{File f = new File(filename);FileReader reader = new FileReader(f);char[] buf = new char[(int)f.length()];int len = reader.read(buf);String results = new String(buf,0,len);String regex = null;if(seperators.length >1 ){regex = "" + seperators + "|" + seperators;}else{regex = "" + seperators;}words = results.split(regex);}public String nextWord(){if(pos == words.length)return null;return words;}
}
