Java中的Math.pow错误

Question

I am 'obviously' just learning programming and I can't seem to figure out what to do in order to get rid if this error. The error is on the second to the last line - the line before: [System.out.print(+windChill);]

Here (written just below), are the list of Java-generated 'possible hints' for the errors that I am getting:

**')' expected

Any hints or clarification would be most appreciated. Please see code below. Thank you in advance.

import java.util.Scanner;
public class Main {

   public static void main(String[] args) {
        // TODO code application logic here
        Scanner input = new Scanner(System.in);
        System.out.print("Enter a temperature between -58 and 41 degrees Fahrenheit and press ENTER");
        double temperature = input.nextDouble();
        System.out.print("Enter a wind speed that is 2 miles per hour or faster and press ENTER");      
        double windSpeed = input.nextDouble();
        double windChill = (((35.41 + temperature - Math.pow(windSpeed * 16) + Math.pow(temperature * 16)));
        System.out.print(+windChill);

    }

}

Answer 1

(((35.41 + temperature - Math.pow(windSpeed * 16) + Math.pow(temperature * 16)))

Math.pow requires two arguments. You are providing just one.

Did you mean Math.pow(windSpeed,16) ?

Math.pow is declared as public static double pow(double a,double b) It returns the value of the first argument raised to the power of the second argument.

In addition you have an extra parenthesis at the left hand side.

Answer 2

The error indicates that you're missing a ) at the end of the line that starts

double windChill = (((35.41 + temperature...

You could also remove one of the ( at the beginning of the expression after the = , since it looks like not all of those are really needed.

Answer 3

Math.pow takes two arguments, in an expression x^y it takes first parameter x and second parameter y , but you're only passing single arguments. Where's your exponent?

Answer 4

You have an extra parenthesis here:

 double windChill = (((
                    ^

either remove that or add a ) at the end.

Answer 5

The Math.pow function needs two arguments, the base and the power. You are only passing in one value - the product of windSpeed and 16. I think you probably mean:

Math.pow(windSpeed, 16)
