How is it to pass "int [] rank" to main method?
public class Card
{
private int [] rank= new int [13];
private String [] suit={"Spades","Hearts","Diamonds","Clubs"};
private static void rankMaker (int []rank)
{
for (int i=1;i<=13;i++)
rank[i]=i;
}
public static void main (String []args)
{
System.out.println("Jack ="+rank[11]);
}
}
Ignoring the way I am making this deck, what I want to know is how generally can I use "int [] rank" (or any other variable declared outside the main) in other methods?

rank[i]=i;
}
public static void main (String []args)
{
System.out.println("Jack ="+rank[11]);
}
}

You can't, period.
The normal way is to have the main method do nothing except handle commandline arguments, create a single instance of the application (usually its own class), and start that instance.

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.

Just in case, here's kindof what he's talking about:
public class Card
{
private int [] rank= new int [13];
private String [] suit={"Spades","Hearts","Diamonds","Clubs"}; //Not used?
public Card()
{
super();
}
public void setRanks(int []rank)
{
for (int i=1;i<=13;i++)
{
rank[i]=i;
}
}
public int getRankAt(int index)
{
return this.rank[index];
}
}
class TestCard
{
public static void main(String[] args)
{
Card c = new Card();
System.out.println(c.getRankAt(11) + "");
}
