java_基于字元緩沖流實作檔案拷貝

代碼如下：

package moose;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;

public class FileCopyTool2 {
    //測試
    public static void main(String[] args) {
        Copyfile2("d:/a.txt","d:d.txt");
    }
    //基于字元緩沖流實作檔案拷貝
    public static void Copyfile2(String src,String des){
        BufferedReader br = null;
        BufferedWriter bw = null;
        try {
            br = new BufferedReader(new FileReader(src));
            bw = new BufferedWriter(new FileWriter(des));
            String temp = "";
            while ((temp=br.readLine())!=null){
                bw.write(temp);
                bw.newLine();   //每次讀一行所有要加換行符
            }
            bw.flush();
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            try {
                if(br != null){
                    br.close();
                }
                if (bw != null){
                     bw.close();
                }
            }catch (Exception e){
                e.printStackTrace();
            }
        }
    }
}
