我想计算索引[0] [2]中的总值,前一个值是0,但我已经用计算结果"1/y"替换并显示它,当我计算总值时,求和的值是先前的值包含"0"的,这是我的代码,

     //observation table
                                     //0             1        2    3      4      5     6                       
     titleColumn = new Object[]{"Time (Second)","Medicine", "1/y","x2", "X/Y", "Y^", "Error"};
                               //0   1    2   3   4   5   6
    allData = new Double[][]  {{1.0,1.02,0.0,0.0,0.0,0.0,0.0},
