Write text to file

Question

Hello,
I have copied some codes about writing text to file as follows:
import java.io.*;
public class Write
  public static void main(String[] args)
    FileOutputStream fos;
    DataOutputStream dos;
    try
      File file1 = new File("C:\\Documents and Settings\\Louis\\My Documents\\MyFile.txt");
      fos = new FileOutputStream(file1);
      dos = new DataOutputStream(fos);
      dos.writeChars("Hello");
    catch (IOException e)
      e.printStackTrace();
}When the java file is compiled, the following compile error occur:
Write.java:17: cannot find symbol
symbol : constructor FileOutputStream(File)
location: class java.io.FileOutputStream
      fos = new FileOutputStream(file1);
1 errorIs that meant File class need to be imported? When I add "import java.io.File;" into the code, I can compile the java file.
But the line "import java.io.*;" is supposed to also import the File class and should not need to add that line. Is my logic correct? Please resolve my question. Thank you.

Sounds like you have a home-made class which you unfortunately named "File", that the compiler sees when compiling your code, rather than thinking that you meant "java.io.File".Yep... to fix that you'll need to remove both File.java and the resulting File.class from your classpath... Just delete File.class, and move or rename File.java.This same thing came up yesterday (with Queue) in this forum, right? Can I have a Friday moan?
A type name is ambiguous if occurs in more than one import:
import java.util.*;
import java.awt.*;
List x; //ambiguous: java.util.List or java.awt.List??
But if it occurs in an import and is defined in the current package, it's quietly assumed we want the type in the current package. I'd rather have this be another ambiguous compiler error, or at least have it generate the appropriate warning.
Couldn't hurt!
