"我是 java\/coding 的新手，我的教授希望我创建一个计算数学函数的应用程序，但我一次只能做一个"

Question

Im trying to set up a program that can do multiple math functions and I can get the first function to work but I have no idea how to set it up so that it can do more than one. The assignment is Utilizing the Java language fundamentals covered in class, create an application that correctly calculates the math functions and produces the expected output. Each number must be represented as a variable.

public class main
{

    public static void main(String[] args)
    {
        int x = -5;
        int y = 8;
        int c = 6;
        int z = x + y * c;
        System.out.println("for the equation ' x + y * c'the sum is" + z);
    }
}

Answer 1

First, I would recommend that you provide a little bit more information about what is being asked of you, since I do not know which math functions you are being asked to implement. Also, the key word here would be functions. I am assuming that your instructor wants you to implement a function that does the specific math problem (adding, subtracting, etc) but I am not sure. In that case, you would have to declare multiple functions in your program, and then call them in the main function. Right now, you are simply writing code inside of the main function, which is why you are unable to do more than one math function at once.
