Can java quickly produce an array with specified values?

Question

In Fortran I can quickly generate an array by typing
Dimension SMF(20,2)
DATA SMF/25*1.,3*0.,9*1.,3*0./
this creates SMF with the value 1 in allocations 1 to 25, 0 in 26 to 27 and so on .
Is there a way for java to do this ?

Answer 1

Not necessarily. Maybe you can write a general Matrix type (an interface) and then write an implementation of Matrix in which its values are specified by an algorithm. So maybe your code would have lines like:
Matrix m1 = new InitWithHardcodedValuesMatrix("{ { 1 2 } { 3 4 }}");
Matrix m2 = new InitWithFormulaMatrix("/25*1.,3*0.,9*1.,3*0./");Or maybe someone has already done this. Have you tried Google?
Anyway, the primary purpose of Java is not formula translation, so it's not surprising that it doesn't have this kind of thing built into the standard libraries.
