Cplex in java: constraint depends on the objective array

I am new to learn cplex in java. As I was trying to solve a special case in which the constraint needs calculation by the IloNumVar array, I met the trouble about how add this calculation into cplex.
The model is
get a matrix m[i][j], for example a 3*3 matrix:
1 2 3
2 1 2
3 2 1
objective: min sum(a[i]) i = {1 ... n}
s.t. a[i] = 0 or 1
b[i] = min (a[i][j]) j = {1 ... n} where a[i] = 1
b[i] <= 2
Is there a way to add this b[i] = min (a[i][j]) j = {1 ... n} where a[i] = 1 into cplex java code? Thanks a lot.

Sorry, but I don't see which are your decision variables, what are the constants? You mention a matrix m, but don't use it? You also use 'a' as a 1-dimensional array in some places and as a 2-dimensional array in others?
