Help!! I dont understand

Question about the task

Under discussion

I get the right output but it doesn't pass Smith:Start game Jones:Start game Gates:Start game Gates:Gather resources Smith:Gather resources Gates:Grow economy Gates:Kill enemies Smith:Grow economy Gates:won! Jones:lost! Smith:lost!

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.

The code inside the run method does not need to check for winning conditions. They should just continue doing their task as defined in the instructions infinitely until a break condition is reached. The trick here is that on lines 39-41 the interrupt() method is called on each object after the loop on line 37 ends when a winner if found. When a thread has had interrupt called on it, the sleep method will throw an InterruptedException. That can be caught by any remaining player objects still running. Knowing this you can break the run method on 2 conditions: The player has won the game; or an exception thrown by sleep is caught in the catch block.
