我不斷收到'非法開始的表達'，我不知道爲什麼

Question

正如在標題中所說的，我在代碼部分的代碼中得到了非法表達式的開始。我相信我把所有的東西都放在正確的位置，但我仍然得到非法的表達。

public class FacebookUsers 
{ 

    public static void main(String[] args) 
    { 
     int months = 1; 

     for (int people = 500000000; people < 2000000000; months ++) 
     { 
      people = (peoplestart) * ((1.05)**(months)); 
     } 

     System.out.println("It took "+months+" to reach one billion users on " 
       + "facebook at the rate of 5% growth."); 
     months = 1; 
     for (int people = 500000000; people < 2000000000; months ++) 
     { 
      people = people * ((1.05)**(months)); 
     } 
     System.out.println("It took "+months+" to reach two billion users on " 
      + "facebook at the rate of 5% growth."); 

    } 

} 

任何幫助表示讚賞，並提前感謝您。

Java沒有**運營商。使用java.lang.Math.pow。
