How do I use a string as an argument to represent an object in Java?

Pardon my lack of knowledge and maybe improper terminology, as I'm new to Java. Here is a simplified version of my code so far:

import javax.swing.ImageIcon;

public class Cards {
    static ImageIcon CA = new ImageIcon("classic-cards/1.png");
}

Also in another class where playerCard[] is an array of JLabels:

String suit = "C";
String rank = "A";
playerCard[playerTurn].setIcon("Cards." + suit + rank);

Obviously setIcon does not use the String as an argument and therefore this will not work. How can I get this to work? Since this is a deck of cards suit and rank will not always be "C" and "A" but I did this for simplification.

Create a Map that contains the String and the Icon.

// Create the Map
HashMap<String, Icon> map = new HashMap<String, Icon>();
...
// Add data to the Map
map.put("Cards.CA", CA);
...
//  Access the Map by your key
setIcon(map.get("Cards." + suit + rank));

As JLabel icon always get the Icon object so you can set the name of icon here and then pass it to your setIcon.There is no overloaded method of JLable#setIcon(String).It has only one method which is JLable#setIcon(Icon).Please Try this

  Icon icon = new ImageIcon("Cards." + suit + rank);
     //here could be any resource path and name like "/foo/bar/baz.png"
    playerCard[playerTurn].setIcon(icon);
