Hello. I've created a Calculator object by adding the line Calculator calculator = new Calculator() in the setup method for this exercise, but when I preview or submit the code, it gives me this compiler error:
symbol: variable calculator location: class CalculatorTest ./com/example/CalculatorTest.java:24: error: cannot find symbol int answer = calculator.addNumbers(1);
Am I creating the new Calculator incorrectly within the setup method, or is it just not running correctly somehow?
package com.example;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
public class CalculatorTest {
@Before
public void setUp() throws Exception {
Calculator calculator = new Calculator();
}
@Test
public void addingMultipleNumbersProducesResult() throws Exception {
int answer = calculator.addNumbers(1 ,2, 3);
assertEquals(6, answer);
}
@Test
public void addingSingleNumberTotalsAppropriately() throws Exception {
int answer = calculator.addNumbers(1);
assertEquals(1, answer);
}
}
package com.example;
public class Calculator {
public int addNumbers(int... numbers) {
int total = 0;
for (int number : numbers) {
total += number;
}
return total;
}
}

Java Web Development Techdegree Graduate 22,175 PointsYou've created calculator
inside setUp
method, that is why it is ONLY available in setUp
method.
In order for it to be available in all tests, you have to declare it as member
of a test class.
Does it makes sense ?
If not please re-watch previous video, and see how Craig defines Creditor creditor
