third requirement error. Can someone help me?

Question about the task

Resolved

I cant resolve the third requirement. Can someone help with?

Three people play the game. Each player (Gamer) is characterized by two parameters: last name (name) and the actions-per-second (rating).
Display the actions taken and determine the winner and the losers.
Let's begin...
1. Figure out what the program does.
1.1. List<String> actions stores the sequence of actions performed by each player from 0 to the last.
1.2. isWinnerFound indicates whether the winner has been found.
1.3. The sleep method throws an InterruptedException and takes a long argument.
1.4. The players play independently of each other.
2. Implement the run method so that for each player:
2.1. At regular intervals (1000ms/rating), the actions specified in the actions list are displayed.
2.2. All text begins with the player's name (getName()), followed by a colon, and then the text itself.

Example:[Smith:Game start].

2.3. When a player has performed all of the actions in the actions list, he or she wins. Display [getName() + ":won!"].
2.4. When the winner is found, the game ends, and the remaining players have lost. For these players, display [getName() + ":lost"].

Don't display the square brackets ("[]").

Requirements:

At regular intervals (1000ms/rating), the Gamer class's run method should display the player's last name (getName()), followed by a colon, and then the text in OnlineGame.actions. Example: [Smith:Game start].
When all the game actions have been completed and the winner has not yet been found, the run method must set the flag OnlineGame.isWinnerFound to true (to inform the others that it is the winner).
If a player wins, his or her run method should display [getName() + ":won!"]. For example: [Jones:won!].
The run methods of all players who did not win (those who were interrupted) should display [getName() + ":lost"]. For example: [Gates:lost]
The run method must not throw an exception when it is interrupted.

useful

@Override
        public void run() {
            //write your code here


            for(String action : OnlineGame.actions){
                    System.out.println(getName() + ":" + action);
                    try {
                        Thread.sleep(1000 / rating);
                    }
                    catch(InterruptedException e)
                    {
                        System.out.println(getName() + ":lost");
                        return;
                    }
                    if(action.equals("Kill enemies") && !OnlineGame.isWinnerFound) {
                        System.out.println(getName() + ":won!");
                        OnlineGame.isWinnerFound = true;
                    }
                }

        }

"for(String action : OnlineGame.actions)" means: for each string action in the actions list. In this for loop, action will be first equal with "Start game", then with "Gather resources", then with "Grow economy" and in the end will be equal to "Kill enemies". So we compare everytime action with "kill enemies" to see if action is the last element in the loop. 1. action("Start game").equals("Kill enemies") -> false 2.action("Gather resources").equals("kill enemies") -> false 3. ... 4. action("Kill enemies").equals("Kill enemies") -> true, then if it is true and the winner is not found (!OnlineGame.isWinnerFound), then System.out.println(getName() + ":won!"); and the winner is found: OnlineGame.isWinnerFound = true; I hope I explained it so you can understand. If you have any questions, please let me know.
