The Java writer question.

/*
     * Iterator Example
     * Example of deleting data called days, months, and days in a list 
     * There are hasnext, next, and remove in the literator. There's a method that does those functions.

package iteator;

import java.util.ArrayList; import java.util.Iterator;

public class IteratorPractice { public static void main(String[] args) { ArrayList list = new ArrayList(); list.add("일"); list.add("월"); list.add("수");

    Iterator iter = list.iterator();


    while (iter.hasNext()==true) {
        String day = (String) iter.next();
        if(day=="number") {
            iter.remove();
        } } System.out.println("Day: "+ day);
    }

System.out.println("============================="); iter = list.iterator();
while (iter.hasNext() == true) { String day = (String)iter.next(); System.out.println("Day: " + day); }

}

}

Question: System.out.println("============================="); on the bottom line Why put iter = list.iterator(); again? Iterator = list.iterator(); on top. And if I have to write it, does it matter if both names are it?
