Changing values to random vin an array

I want to ask the user if they want to hold the cards or not,if the user want to hold cards, change other cards to a random cards (change suits and ranks).And i want to print out all the cards after changes.The rule is the same as normal video poker.

import java.util.Random;
import java.util.*;
import java.util.Arrays;


public class Card
{
String[] suits = { "hearts", "spades", "diamonds", "clubs" };
String[] ranks  = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9","10","Jack", "Queen", "King" };
Random suit = new Random();
Random rank = new Random();

public String getSuitsArrayElement()
{

    return suits[suit.nextInt(suits.length)];  

}
public String getRanksArrayElement()
{
    return ranks[rank.nextInt(ranks.length)];   
}

 public changecard()
{

}
}
import java.util.Scanner;
public class VideoPokerSimulator
{
  public static void main(String[] args)   
{
  Card one= new Card();
  Scanner q = new Scanner(System.in);
    for(int i=0; i<5; i++)
  {
        String a=one.getSuitsArrayElement()+one.getRanksArrayElement();
        System.out.println(a);
  }
 System.out.println("Which cards do you want to hold?");
 String i = q.next();

}
}
