这里书中写的是charactorProcess(File file, String destFile)
这里被我改成，（String file, String destFIle）
一个代表现有的文件和要新建的文件
代码：
package com;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.File;import java.io.FileReader;import java.io.FileWriter;import java.io.IOException;import java.util.HashMap;public class FileRead {public static String replace(String line){//创建一个HashMap存储全角和半角字符之间的对应关系HashMap map = new HashMap();map.put("，", ",");map.put("。", "."); map.put("〈", "<"); map.put("〉", ">"); map.put("｜", "|"); map.put("《", "<"); map.put("》", ">"); map.put("［", "["); map.put("］", "]"); map.put("？", "?"); map.put("＂", "\&;"); map.put("：", ":"); map.put("﹑", ","); map.put("（", "("); map.put("）", ")"); map.put("【", "["); map.put("】", "]"); map.put("－", "-"); map.put("￣", "~"); map.put("！", "!"); map.put("｀", "`"); map.put("１", "1"); map.put("２", "2"); map.put("３", "3"); map.put("４", "4"); map.put("５", "5"); map.put("６", "6"); map.put("７", "7"); map.put("８", "8"); map.put("９", "9"); int length = line.length(); for(int i = 0; i < length; i++){ String charat = line.substring(i, i + 1); if(map.get(charat) != null){ line = line.replace(charat, (String)map.get(charat)); } } return line;}public static File charactoProcess(String string, String destFile){try{//创建一个输出流，用于写新文件BufferedWriter writer = new BufferedWriter(new FileWriter(destFile));//创建一个输入流，，用于读取文件BufferedReader reader = new BufferedReader(new FileReader(string));String line = reader.readLine();while(line != null){//调用replace方法替换所有的全角字符String newline = replace(line);//将替换后的String写入新的文件writer.write(newline);//写入行分隔符writer.newLine();line = reader.readLine();}reader.close();writer.close();}catch(IOException e){e.printStackTrace();}return new File(destFile);}public static void main(String[] args) {// TODO Auto-generated method stubFileRead b = new FileRead();b.charactoProcess("E:\\Lucene项目\\钢铁是怎么样练成的.txt", "E:\\Lucene项目\\目标文件.txt");}}
你曾经说，等我们老的时候，
