I want to calculate total value in index [0][2], previous value is 0, but I have replaced and display it with the calculation result “1/y”, and when I calculate total value, value that summed is previous value that containing “0”, this my code, -
-
//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},
-
{2.0,0.667,0.0,0.0,0.0,0.0,0.0},
-
{3.0,0.367,0.0,0.0,0.0,0.0,0.0},
-
{4.0,0.278,0.0,0.0,0.0,0.0,0.0},
-
{5.0,0.237,0.0,0.0,0.0,0.0,0.0},
-
{6.0,0.187,0.0,0.0,0.0,0.0,0.0},
-
{7.0,0.155,0.0,0.0,0.0,0.0,0.0},
-
{8.0,0.156,0.0,0.0,0.0,0.0,0.0},
-
{9.0,0.142,0.0,0.0,0.0,0.0,0.0},
-
{10.0,0.111,0.0,0.0,0.0,0.0,0.0},
-
{11.0,0.12,0.0,0.0,0.0,0.0,0.0},
-
{12.0,0.097,0.0,0.0,0.0,0.0,0.0},
-
{13.0,0.099,0.0,0.0,0.0,0.0,0.0},
-
{14.0,0.089,0.0,0.0,0.0,0.0,0.0},
-
{15.0,0.079,0.0,0.0,0.0,0.0,0.0},
-
{0.0,0.0,0.0,0.0,0.0,0.0,0.0}};
-
-
tableModelObservation = new DefaultTableModel(allData, titleColumn);
-
tableObservation.setModel(tableModelObservation);
-
int row,column,inputRow,inputColumn;
-
-
//index [0][2] was replaced with calculation 1/y
-
row = 0;
-
column = 1;
-
inputRow = 0;
-
inputColumn = 2;
-
double onePerY = 0;
-
for(int a=0;a<allData.length;a++){
-
onePerY = 1/allData[row][column];
-
tableObservation.getModel().setValueAt(onePerY, inputRow, inputColumn);
-
inputRow++;
-
row++;
-
}
-
-
//calculation total 1/y, summing is still using previous value "0"
-
row = 0;
-
column = 2;
-
inputRow = 15;
-
inputColumn = 2;
-
double totalOnePerY = 0;
-
for (int a=0;a<allData.length;a++){
-
totalOnePerY += allData[row][column];
-
row++;
-
}
-
//displaying result in row index[15] and column index[2]
-
tableObservation.getModel().setValueAt(totalOnePerY, inputRow, inputColumn);
-
this column values ”1/y” after calculation process 
What should I do, to be able to summing it using new value ?
all the assistance that you gave, I would appreciate it, thank you
