New to Java

Hello everyone!

I need to write program which does integral calculations with indefinite integrals, i for example enter function and it gives out summary value of function? For example if i have integral calculation function like (4x-3)dx/(x^2-5x+1), i want just enter it, and it performs calculations and gives out summary value! I think its quite hard to do! isn't there any library i could import like java.math or smthn like that which ease the task?

Thanks
