在Java中怎样利用输出输入流将一个记事本中的内容写入另一个记事本中.谁给我做个答案!

大体思路如下...楼主可以试试

public static void main(String[] args) {
try {
FileReader reader = new FileReader("d:/file.txt");//流出文件
BufferedReader br = new BufferedReader(reader);
FileWriter writer = new FileWriter("d:/file1.txt");//流入文件
BufferedWriter bw = new BufferedWriter(writer);
String str;
while (br.ready()) {
str = br.readLine();//逐行读出
bw.write(str);//逐行写入
bw.newLine();//换行
}
br.close();
bw.close();
reader.close();
writer.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

import java.io.*;
public class TestFileOutputStream {
public static void main(String[] args) {
int b = 0;
FileInputStream in = null;
