摘要: 一个JAVA题帮我看一下呀

import java.io.FileInputStream;
import java.io.DataInputStream;
import java.io.IOException;
public class Windows
{
public static void main(String[] args)
{
try
{
FileInputStream fis=new FileInputStream("c://WINDOWS//win.ini");
DataInputStream dis=new DataInputStream(fis);
dis.readInt();
dis.close();
}catch(IOException e){}

}
}

要求编写一个JAVA程序读取WINDOWS目录下的win.ini文件，并打印输出其内容。
谢谢了各位

BufferedReader br = new BufferedReader(new InputStreamReader(fis));
//DataInputStream dis=new DataInputStream(fis);
StringBuffer strb = new StringBuffer();
String temp = "";
while((temp = br.readLine()) != null)
