Help to create an appropriate cursor

[shean1488]

Hi everybody,

I want to have some kind of a cursor in my program. My goal is: everytime when I write a getName() method I want it to return a next value. But the thing is I don't want to delete any elements befour. So please help me to give an idea how I can achieve it or write some sample.

here is the code:

import java.io.PrintStream;
import java.util.*;

public class Table {
	
	static Set<String> mySet = new LinkedHashSet<String>();
	
	public static void main(String[] args) {
		System.out.println("Please enter 3 names");
		for(int i=0; i<3; i++)
			setName();
                System.out.println("");
		getName();
                getName(); // when I call this and the next method
                getName(); // I want to have different output
	}
	public static void setName() {
		Scanner input = new Scanner(System.in);
		String str = input.next();
				
		while(!mySet.contains(str)) {
			mySet.add(str);
		}
	}
	public static PrintStream getName() {
		Iterator<String> itr = mySet.iterator();
		String str = itr.next();
		return System.out.printf("%s\n",str);
	}
	
}

right now my output looks like this :

Please enter 3 names
Bob
Sam
Ron
Bob
Bob
Bob

But I want it to be like this:

Please enter 3 names
Bob
Sam
Ron
Bob
Sam
Ron
