LeetCode報錯一： cannot find symbol [in __Driver__.java]

錯誤介紹

Line 10: error: cannot find symbol [in __Driver__.java]
      int ret = new Solution().calculate(param_1);
                              ^
  symbol:   method calculate(String)
  location: class Solution

錯誤原因

我的類名和方法名太像了，Solution與solution

更正

就讓他們不像，取過其他名字就好啦！
