getUpperBound() Java

I am running tests on range methods in java and am trying to get the upperbound of a range of inputs. I have this so far: package org.jfree.data.test;

import org.jfree.data.Range;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;

import junit.framework.TestCase;

public class IntersectsTest extends TestCase {

    
    private Range range;


@Before
public void setUp() throws Exception {
     range = new Range (-2.00, 2.00);
    
  
    }


@After 
public void tearDown() throws Exception {

}

@Test
public void testgetupperbound() {
     
     double result = range.getUpperBound();
     System.out.println(result);
        }}

The resulting output should be 2.00 but the console outputs -2.00
