[Help-glpk] java-binding: zero-coefficients

I am using the java-binding for glpk and
want to solve an LP which also has zero-coefficients. 

I read that this is no valid input. Is there a workaround for that? 

I am no mathematician but I assumed there is
no mathematical reformulation for eliminating the zeros. Correct?

I read in the User's Guide under glp_new_aij 
that zero coefficients do not need to be specified.
(Any non specified coefficients are assumed to be zero.) 
Is this correct?

How is it with the java-binding? Is there a way too? 
(I have not found any possibility to enter single coefficients.) 

Many thanks in advance,
