Hi Tim,
The "import" statement lets you save a bit of typing. When you import a Java class, you can use the class name without having to specify the package name every time.
For example, consider the following Java code:
java.util.Properties props = new java.util.Properties();
props.setProperty("merchantID","v2348705");
java.util.HashMap request = new java.util.HashMap();
request.put( "ccAuthService_run", "true" );
If you had a lot of these "java.util.Properties", "java.util.HashMap" classes in your program, it might become cumbersome to keep typing "java.util.Properties" over and over again. Lots of typing. So you'd use an import statement to make it easier. If I import java.util.Properties, then I don't have to type "java.util" every time I use it:
import java.util.Properties;
import java.util.HashMap;
Properties props = new Properties();
props.setProperty("merchantID","v2348705");
HashMap request = new HashMap();
request.put( "ccAuthService_run", "true" );
You can use an asterisk ("star") character as a wildcard if you want to import all classes in a given package. That's what your sample does.. So instead of individually listing every class I want to use, I could do this:
import java.util.*;
Properties props = new Properties();
props.setProperty("merchantID","v2348705");
HashMap request = new HashMap();
request.put( "ccAuthService_run", "true" );
This lets me import both java.util.Properties and java.util.HashMap in one go. I can also use any other java.util.xxxxx class the same way, no need to manually import them all.
So that's what import does. You could certainly re-write your code in RPG. You'd have to continue to call the Properties, HashMap and Client classes in Java, however. Unless there's a way to replace that Client altogether with something written in ILE?

Hello,
I have a java credit card valiation program that I wish to convert to rpg.
I've seen several posts on calling java methods and such, but can it be done
with the following code. If so, can someone provide some examples. I guess
the most confusing part is the "import" section.
Thanks.
