为什么我的代码不起作用（java netbeans）？

Question

i want the code to calculate the netpay formula. This is the code I used, it has no errors in the program but when I run it, it just says build success and doesn't calculate.

package com.mycompany.netpay;

public class NetPay {

    public static void main(String[] args) {

    }
    double h = 40;
    double i = 2.00;
    double t = 0.22;
    double w = 5.00;
    double result = (h * w - i) - t * (h * w - i);
}

Answer 1

Typically you need your code within the method, not out of it. Try this:)

package com.mycompany.netpay;

public class NetPay {

    public static void main(String[] args) {
        double h = 40;
        double i = 2.00;
        double t = 0.22;
        double w = 5.00;
        double result = (h * w - i) - t * (h * w - i);
        // System.out.println(result);
    }
}

You're not logging this out to the console or system however, so you may still not see a result. Search "How to print to system in Java" for more information.
