Is the any way one can represent a very large number in java.

[thatos]

I'm trying to write an algorithm which determines the shortest path between cities. So I have looked at some high level languages of the algorithms, if the is no path between two vertices, they represent this by infinity, is there any way I could represent a very large number in java?

What type are you using to represent distance? Consider:

Integer.MAX_VAL UE

or

Double.POSITIVE _INFINITY

For those 'big M' values usually no large numeric values are used. Sentinel
values such as -1 do a better job.

kind regards,
