[問題] 同樣程式碼 執行結果怎麼會不一樣

[Happyboy101 (風雨同路共送呂布)]

class Miracle
{
    public static void main(String args[])
    {
        int Graph[][]={{0,1,1,1,0,0,0,0,0,0,0,0,1},{1,0,1,1,0,0,0,0,0,0,0,0,0},
                       {1,1,0,1,0,0,0,0,0,0,0,0,0},{1,1,1,0,1,1,0,0,0,0,0,0,1},
                       {0,0,0,1,0,1,1,0,0,0,0,0,0},{0,0,0,1,1,0,1,1,1,0,0,0,0},
                       {0,0,0,0,1,1,0,1,0,0,0,0,0},{0,0,0,0,0,1,1,0,1,0,0,0,0},
                       {0,0,0,0,0,1,0,1,0,1,0,0,0},{0,0,0,0,0,0,0,0,1,0,1,0,0},
                       {0,0,0,0,0,0,0,0,0,1,0,1,0},{0,0,0,0,0,0,0,0,0,0,1,0,0},
                       {1,0,0,1,0,0,0,0,0,0,0,0,0}
                     };
        //執行這段程式碼 會跑出ArrayIndexoutOfBoundsexception
      /*int i,j;
        for(i=0;i<13;i++)
        {
          for(j=0;j<13;j++);
            System.out.print(Graph[i][j]);
          System.out.println();
        }
      */

        //若採用這段程式碼 卻是順利執行
        //但這兩段程式明明是一模一樣的 怎麼會結果差很多
        //這可以算是奇蹟嗎? 還是這兩段程式有不同之處?希望有人能解惑 謝謝
        int i,j;
        for(i=0;i<13;i++)
        {
          for(j=0;j<13;j++)
            System.out.print(Graph[i][j]);
          System.out.println();
        }

    }
}
