其他人無法找到If語句，即使有一個

Question

當我嘗試編譯此代碼時，我得到一個錯誤，說如果沒有if。我相信我擁有正確的地方所有的大括號。我還得到了其他的錯誤信息，但我只相信他們在那裏，因爲如果錯誤不能使用其他錯誤。

問題代碼：

public static boolean goNorth(){ 
     boolean success; 
     if(maze[currCol]currRow - 1] == CLEAR){ 
      maze[currCol][startRow -1] = PATH; 
      currRow--; 
      success = goNorth(); 
       if(!success){ 
       success = goWest(); 
        if(!success){ 
        success = goEast(); 
         if(!success){ 
          maze[currCol][currRow] = VISITED; 
          currRow++; 
          } 
         } 
        } 
        return success; 
       } else { 
        return false; 
      } 
     } 

    public static boolean goWest(){ 
     boolean success; 
     if(maze[currCol - 1]currRow] == CLEAR){ 
      maze[currCol - 1][startRow] = PATH; 
      currRow--; 
      success = goWest(); 
       if(!success){ 
       success = goSouth(); 
        if(!success){ 
        success = goNorth(); 
         if(!success){ 
          maze[currCol][currRow] = VISITED; 
          currCol++; 
          } 
         } 
        } 
        return success; 
       } else { 
        return false; 
      } 
     } 

     public static boolean goEast(){ 
     boolean success; 
     if(maze[currCol + 1]currRow] == CLEAR){ 
      maze[currCol + 1][startRow] = PATH; 
      currRow--; 
      success = goEast(); 
       if(!success){ 
       success = goNorth(); 
        if(!success){ 
        success = goSouth(); 
         if(!success){ 
          maze[currCol][currRow] = VISITED; 
          currCol--; 
          } 
         } 
        } 
        return success; 
       } else { 
        return false; 
      } 
     } 

     public static boolean goSouth(){ 
     boolean success; 
     if(maze[currCol]currRow + 1] == CLEAR){ 
      maze[currCol][startRow + 1] = PATH; 
      currRow--; 
      success = goSouth(); 
       if(!success){ 
       success = goEast(); 
        if(!success){ 
        success = goWest(); 
         if(!success){ 
          maze[currCol][currRow] = VISITED; 
          currRow--; 
          } 
         } 
        } 
        return success; 
       } else { 
        return false; 
      } 
     } 

錯誤：

Answer 1

if(maze[currCol + 1]currRow] == CLEAR){ 

這不是有效的;你在幾個地方錯過了左邊的支架currRow。

此外，還有一大塊的重構。

Answer 2

首先閱讀錯誤。在第一個錯誤之後，不要再讀取任何錯誤，直到您理解第一個錯誤。

的第一個錯誤是告訴你，你在這一行有一個語法錯誤：

if(maze[currCol]currRow - 1] == CLEAR){ 

（你再複製粘貼四次）。在currRow之前缺少[。
