Refer to that Red planet Object...(outside the method it's in)

nomad

Hello Everyone:
I back trying to learn Java again.
Here is what I'm trying to do.
1. How does the code inside the visitPennsylvania method refer to the variable with vale "red Planet".
I know to that you need to use. this.
But I can not figure out how to use it.
Here are my two class.

Expand|Select|Wrap|Line Numbers

  import static java.lang.System.out; 

public class EnglishSpeakingWorld {

String mars = " red planet";

void visitPennsylvania() {

out.println("visitPA is running:");

String mars = "Janine's home town";

out.println(mars);

out.println(this.mars);
 
}

Expand|Select|Wrap|Line Numbers

  import static java.lang.System.out; 

public class GetGoing {

public static void main (String args[]) {

out.println("main is running:");

EnglishSpeakingWorld e = new EnglishSpeakingWorld();

out.println(e.mars);

e.visitPennsylvania();
 
}

Thanks

Works for me. Are you sure you compiled and ran your latest version?

To much reading and I'm tried.
I was think from the [color=#000000]class[/color] GetGoing.
to println this.mars
