我想写个从网上下载文件的程序
--------
File inputFile = new File("http://community.csdn.net/Expert/topic/3420/3420081.xml");
File outputFile = new File("c:\\2.txt");

FileReader in = new FileReader(inputFile);
FileWriter out = new FileWriter(outputFile);
int c;
while ((c = in.read()) != -1)
out.write(c);
in.close();
out.close();
----------------------------
错误如下
java.io.FileNotFoundException: http:\community.csdn.net\Expert\topic\3420\3420081.xml

at java.io.FileInputStream.open(Native Method)

at java.io.FileInputStream.<init>(FileInputStream.java:103)

at java.io.FileReader.<init>(FileReader.java:55)


at test_1.ok_1.main(ok_1.java:43)

Exception in thread "main"

import java.io.*;
public class test1{
public static void main(String[] args){

try{
File f = new File("TextFile.txt");
FileInputStream fis = new FileInputStream(f);
FileOutputStream fos = new FileOutputStream("b.txt");
int i;
while((i = fis.read()) != -1){
fox.write(i);
}
fis.close();
fox.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
}

File f = new File("http://community.csdn.net/Expert/topic/3446/3446976.xml");
-----------------------------------------------
还是：
java.io.FileNotFoundException: http:\community.csdn.net\Expert\topic\3446\3446976.xml
at java.io.FileInputStream.open(Native Method)

at java.io.FileInputStream.<init>(FileInputStream.java:103)

at test_1.ok_1.main(ok_1.java:79)

Exception in thread "main"
