Trying to conceptualize a way of coding for my game

First off I'm using Jpanel to create a game with an interface and playing field with around 30 - 40 hexes. Each hex is a label / image and has a 3 methods that are listeners for exit / press / click.

The problem is that each hex needs to use a ton of variables and I don't want to code an individual set of variables for each hex.

example:
lumberHex1, lumberHex2, lumberHex3

as an example I want to set 'boolean lumber' and 'boolean discovered' to be true only inside that method.
Local variables aren't working...

I'm afraid I don't quite understand an easy way of doing this. 'boolean discovered' and 'boolean lumber' are declared at the top of the class, I need a variable that can be named the same but hold different values for each method?

Hopefully I am making some sense, and there is just a flaw in my logic - or there is another way of doing this - any help would be greatly appreciated.

private void jLabel57MouseClicked(java.awt.event.MouseEvent evt) {
 randomResource rg = new randomResource();
        rg.setResource(lumber, brick, coin , grain);
        
        //boolean discovered;
        if (clicked == false) {
            rg.genNum();
            
            System.out.println(rg.resourceValue);
            if (rg.resourceValue.equals("lumber")) {
                jLabel57.setIcon(new ImageIcon("src/hexTree.png"));
                System.out.println("Lumber has been placed here? = " + rg.isLumber);
                discovered = true; // right here
                lumber = true; // right here
                rg.setAll(clicked = true);
                rg.returnLumber(lumber);
                if(villagerAmount <= 0 )
                {
                    jLabel57.setIcon(new ImageIcon("src/hexTreeRedFull.png"));
                }
                if(villagerAmount >= 1)
                {
                    jLabel57.setIcon(new ImageIcon("src/hexTreeCutting.png"));
                    harvestReady = true;
                    
                    ActionListener taskPerformer5 = new ActionListener() {
                public void actionPerformed(ActionEvent evt) {
                    
                    while(buffRemaining >= 0) {
                        resource1Amount++;
                        buffRemaining--;
                    }
                    if (buffRemaining <= 0) {
                        harvesting  = false;
                    }
                }
            };
            new Timer(delayThreeTwo, taskPerformer5).start();

            villagerAmount--;
            villagers.setText("Villagers: " + villagerAmount);      
                } 
            }
