关于从Jtable中取数到多维数组的问题

Question

int row=0;
for(int i=0;i<v.length;i++){
for(int j=0;j<v[i].length;j++){
for(int k=0;k<v[i][j].length;k++){
for(int l=0;l<v[i][j][k].length;l++){
v[i][j][k][l]=new Variable();
v[i][j][k][l].setTheta(Double.parseDouble((String)tableModel.getValueAt(row, 0)));
v[i][j][k][l].setTal(Double.parseDouble((String)tableModel.getValueAt(row, 1)));
v[i][j][k][l].setDegreeOfMembership(Double.parseDouble((String)tableModel.getValueAt(row, 2)));
v[i][j][k][l].setNonDegreeOfMembership(Double.parseDouble((String)tableModel.getValueAt(row, 3)));

row++;

}
}
}
}
这是代码，跪谢各位大神
主要是想问row++好像无效，我一运行就报错了，说空指针异常
