Hey guys i have a problem, I would like to assert that when i input 2 specific strings that an array is returned. I want to use the assert statement and parameterized testing to do this however my current assert statement is showing an error, iv placed my code below please help:

import IT_chatbot.drop_course;

 @RunWith(Parameterized.class)
 public class drop_course_test {

 drop_course check;

    @Before
    public void setUp() throws Exception {
        check= new drop_course();
    }

            private String[] output;
            private String input1;
            private String input2;

        public drop_course_test(String output[],String input1,String input2 )
        {
            this.output=output;
            this.input1=input1;
            this.input2=input2;
        }

        @Parameters
        public static Collection testConditions(){

            String[] droplist1={"ITE222 Web Development 2","ITE365 Software Quality Management","ITE446 Current Topics in Software Engineering","ITE220 Programming 1"};

            return Arrays.asList(new Object [][]{
                    {droplist1, "216110116","ITE200"},

            });
        }
    @Test
    public void test() {
        assertEquals(output, drop_course.drop(input1, input2));
    }

}
