E and PI are not functions, they're static fields (data members). That code will output their values correctly. You don't have to import anything, the Math class is in the java.lang package, which is imported by default. (It's the only package imported by default, I believe.)

Java math libraries?
Apache Math has a polynomial fitter. It also has a linear solver and lots of other useful bits. I haven't used a symbolic math solver in Java. It's not quite the same, but I did use Z3 with Java this year, there is z3-turnkey that provides a helpful Maven dependency for that. More on reddit.com

High performance library for linear algebra
My experience is a few years old now but I doubt much has changed. For smallish matrices, EJML https://github.com/lessthanoptimal/ejml is the fastest. There are other libraries ( https://jblas.org/ ) that are faster for large matrices, but they involve sending your matrix out of the JVM to an optimized C library, which causes a good deal of overhead. EJML is pure java, so there's no overhead. More on reddit.com
