java io 的问题,请高手指点
import java.io.*;

public class TestBufferedWriter {
public static void main(String args[]) {
String name = "弄风尘.txt";
String path = "d:/wowo/";
String s = "我爱北京*，*上太阳升！";
BufferedWriter bw = null;
try {
File f = new File(path + name);
bw = new BufferedWriter(new FileWriter(f));
bw.write(s);
bw.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
}
控制台输出为
java.io.FileNotFoundException: d:\wowo\弄风尘.txt (系统找不到指定的路径。)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(Unknown Source)
at java.io.FileOutputStream.<init>(Unknown Source)
at java.io.FileWriter.<init>(Unknown Source)

------解决方案--------------------
你这样只是创建文件，不会创建目录，创建目录看下面的程序

Java code

import java.io.*;

public class TestBufferedWriter {
    public static void main(String args[]) {
        String name = "弄风尘.txt";
        String path = "d:/wowo/";
        String s = "我爱北京*，*上太阳升！";
        BufferedWriter bw = null;
        File folder=new File(path);
        if(folder.exists()){
            if(!folder.isDirectory()){
                folder.mkdir();
            }
        }
        try {
            File f = new File(path + name);
            bw = new BufferedWriter(new FileWriter(f));
            bw.write(s);
            bw.flush();
            bw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
