You can write Java programs to perform math calculations, solve equations, plot graphs etc, but that requires you to understand what you are trying to do. If you don't undertand the math, writing a Java program isn't going to help, in fact it will just add a whole load of confusion.
Have a look on the web, there are many sites that will teach you any math topic you want. Once you understand the concepts and equations you can start to use Java to perform the calculations.
