Explanation / Answer

Hi, In the above code "Method to rotate hexagon" is incomplete with errors.

public void rotate(){
       char temp = section[0];
       for(int i=1;i            section[i-1] = section[i];
       }
       section[section.length -1] = temp;
   }

java:106: error: ';' expected
for(int i=1;i section[i-1] = section[i];
