Java programming

[Johny5]

Hi,There.
I am a new to Java programming.I teach myself Java Programming.I learn from a book calls "Learn Java Now J++" By Stephen R.Davis and a Microsoft Visual J++ version 1.1 to write a program. My very first program as following...

public class Appl_1
{
public static void main(String args[])
{
System.out.println("Hello,world");
}
}

and I saved as Appl_1.java. When I compile it, It says error J0051: Undefined package 'lang' .I got stuck right here. I can not execute the program.

Could you help me to solve this problem ?.I am appreciate it very much.Thanks./.

What are your imported packages? Also are using the command line compilier or an IDE based compilier, nevermind I saw it's MS J++ so it's IDE. See if you could find the package paths, it's been a while since I used this, and make sure that package exists. Also when you set up the project what type did you pick, if I remember correctly J++ gives you the option to use WFC or JAVA, and the packages it defaults to will vary. Again it's been a while since I used J++ so take what I said with a grain of salt.

Ultimatly though you have a package imported that it can't find. Delete the import line or find the package and set the right path.
