how can I make this snake and ladder java program running round by round
<p>Hi guys I have coded a snake and ladder game, it works fine, however, there is one question I don't know how to settle. currently, the game is running by rolling the die continuously, and I don't have control over each round. I am thinking about how to control the game round by round, so I can manually set the die value for each round and do some test. please give me some help, thank you.</p>
