java - Expression expected after this token -

why popping up?

syntax error on token "+", expression expected after token

for (int row = 0; row < data.length; row++) {   (int col = 7;;) {             data[row][col] = [row][1] + [row][2] + [row][3] + [row][4] + [row][5] + [row][6];     }for (int col = 8;;) {             data[row][col] = formatter.format(([row][7] / 2650) * 100);    } } 

it appears on every plus sign , equals after data[row][col] =.

the [row][col] access expression array, need specify array want access on these indices. therefore every of statements indices should start data

for (int row = 0; row < data.length; row++) {     (int col = 7;;) {         data[row][col] = data[row][7] + data[row][2] + data[row][3] + data[row][4] + data[row][5] + data[row][6];     }     (int col = 8;;) {         data[row][col] = formatter.format((data[row][7] / 2650) * 100);     } } 

for more information , examples see java tutorial on arrays.

also notice have 2 infinite loops, guess code incomplete or loops redundant

for (int row = 0; row < data.length; row++) {     data[row][7] = data[row][1] + data[row][2] + data[row][3] + data[row][4] + data[row][5] + data[row][6];     data[row][8] = formatter.format((data[row][7] / 2650) * 100); }
