In this section of tutorial we will learn how to use the Map with the Iterator interface. We will create an example to display the contents of the map using Iterator
import java.util.*; public class map1 { public static void main(String[] args) { Map map = new TreeMap(); char grade[] = { 'a', 'b', 'c', 'd' }; int x = 1; for (char c : grade) { map.put(x, c); x++; } Set s = map.entrySet(); Iterator i = s.iterator(); while (i.hasNext()) { System.out.println(i.next()); } } }
Output :
1=a 2=b 3=c 4=d
