JAVA 檔案讀取

人老了, 太多寫過的都記不得了

import java.io.*;

public class readfile
{
public static void main (String args[])
{

try
{
FileReader fw= new FileReader(args[0]);
BufferedReader buf = new BufferedReader(fw);
String s;
while ( (s=buf.readLine() ) != null)
System.out.println(s);
buf.close();
}
catch (IOException e)
{
System.out.println("Error: " + e.toString());
}
}
}
