Iterate through hashtable in java

To iterate through hashtable in java, first we have to get all keys as set object and then fetch each element using key.

Example:

package com.w3spoint;
 
import java.util.Hashtable;
import java.util.Set;
 
public class Test {
  public static void main(String args[]){
	//Create Hashtable object.
	Hashtable<String, String> hashtable = new Hashtable<String, String>();
	//Add objects to the Hashtable.
	hashtable.put("1", "Jai");
	hashtable.put("2", "Mahesh");
	hashtable.put("3","Vivek");
        System.out.println(hashtable);
        Set<String> keys = hashtable.keySet();
        for(String key: keys){
            System.out.println("Value of "+key+" is: "+hashtable.get(key));
        }
  }
}

Output

{3=Vivek, 2=Mahesh, 1=Jai}
Value of 3 is: Vivek
Value of 2 is: Mahesh
Value of 1 is: Jai
