cannot comile user defined classes

Hello i have a problem on compiling user defined classes .

example

file x.java

public class x{

...........................

}

file y.java

import x;

public class y{

}

I first compile x.java and everything is OK .

Then i compile y.java and the compiler gives the folowing

y.java:2: '.' expected

import y

I have tried to put the classes on a package and added the folowing line yo each file

import /home/bill/test

Then i puted the java files on that dir

and compiled with

javac -classpath /home/bill/test y.java

AGAIN THE SAME

y.java:2: '.' expected

import y
