Answer 1

package one;

import java.util.*;

public class One {

public static void main(String[] arr) {

/* Create object of HashMap */

HashMap<String, String> obHashMap = new HashMap<String, String>();

/* Store value in HashMap */

obHashMap.put("Bhutan", "Thimphu ");

obHashMap.put("China", "Beijing ");

obHashMap.put("India", "New Delhi ");

obHashMap.put("Israel", "Jerusalem ");

obHashMap.put("Japan", "Tokyo ");

/* Create a set of keys of hashmap */

System.out.print("COUNTRY"+ ": ");

System.out.println("CAPITAL");

Set set=obHashMap.entrySet();

Iterator obIter = set.iterator();

while (obIter.hasNext()) {

Map.Entry me=(Map.Entry)obIter.next();

System.out.print(me.getKey() + ": ");

System.out.println(me.getValue());

}

}
