我正在嘗試創建賽馬博彩遊戲。我無法比較各匹馬的價值,看看哪一匹獲勝。運算符>未定義爲參數類型java.util.Random,java.util.Random
在if語句我嘗試比較horse1的值和horse2和horse3的值。但我得到的錯誤: 他操作>未定義的參數類型java.util.Random中,java.util.Random的

隨機馬1 =新隨機(100); ** **不會使馬1成爲一個隨機數達100(這是它看起來像你正在做的事情)。你只需要1個「隨機」對象,那麼馬1,馬2等將是整數或什麼,你分配他們像'horse1 = myRandom.nextInt(100);' – csmckelvey
