its giving me following error and i have jdk6 installed.
===
javac: file not found: com\wickedlysmart\MyClass.java
Usage: javac <options> <source files>
use -help for a list of possible options

but in book page# 793 the error message is different!


Note: i have give wrong value to -d param "classes1" which is not available onto file system and while compiling through "javac -d ../classes com/wickedlysmart/MyClass.java" its just compiling fine, no error.

Hi , I am getting the following message while compiling like you. instead of classes i am using classes1 which doesn't exist. I think this is similar to what book mention. I have JDK5.

C:\myProject\source> javac -d ../classes1 com/wickedlysmart/MyClass.java
com/wickedlysmart/MyClass.java:2: error while writing com.wickedlysmart.MyClass:
..\classes1\com\wickedlysmart\MyClass.class (The system cannot find the path sp
ecified)
public class MyClass{
^
1 error

I changed my JDK to 1.6 now message is same like in book.

C:\>java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode)

C:\>cd myProject

C:\myProject>cd source

C:\myProject\source>javac -d ../classes1 com/wickedlysmart/MyClass.java
javac: directory not found: ../classes1
Usage: javac <options> <source files>
use -help for a list of possible options

@Rajiv

I am not entirely sure of the reason why you are trying to reproduce the issue. The original poster of this topic already mentioned that the issue was found, and that it compiles now...

Hi,

Issue is he is not getting the right error message if he provide wrong direcotry name. Error should say directory not found but he is getting file not found what he is trying to compile.

If directory exists he compiles just fine.
But if directory not exists he is getting different message than book.( thats why i was compiling on my system and I am getting similar answer as on book).

change the directory name to anything that is not there like classes you will get direcctory not found error.
$ javac -d classes1 com/wickedlysmart/MyClass.java
javac: directory not found: classes1
Usage: javac <options> <source files>
use -help for a list of possible options
