Java, Cannot find symbol error?

Question

I am trying to compute the total price given the unit price, 17, and the number of items, 20.

public class hw1_task3 {
    public static void main(String[] args) {
        int total = units * price;
        int units = 20;
        int price =  17;
        System.out.printf("The total is: %d", total);
    }    
}

What is wrong with the program? I keep getting an error about not being able to find the symbols. I am very new to java, any help is greatly appreciated.

Answer 1

You need to move units and price above total like this:

int price =  17;
int units = 20;
int total = units * price;

Answer 2

You are using the variable before the declaration. These lines

int units = 20;
int price =  17;

should be written first and

int total = units * price;

after that.
So the correct lines will be:

int units = 20;
int price =  17;
int total = units * price;
