I am confedent that the code was right
is there somthing i must do after comand promp returns

I am confedent that the code was right
Really? The code above does not compile, there are lots of errors in it:
- You need a ";" after "package je3.basics"
- It is "String", not "string" (Java is case-sensitive)
- It is "System", not "system"
- The method you want to call is not called "printin", but "println"
- You should save this is a file called "hello.java", not "helloworld.java", because the class is called "hello"
- You should save this file in a subdirectory "je3\basics" because of the package statement
Then you compile it like this (assuming you saved the file in C:\MyProject\je3\basics):
C:\MyProject> javac je3\basics\hello.java
And you run it like this:
C:\MyProject> java je3.basics.hello
