Java j-unit. Помогите с задачкой :)

Question

class PalindromeService { 
    public boolean isPalindrome(String text) { 
        String reversedText = new StringBuilder(text).reverse().toString(); 
        return text.equals(reversedText); 
    } 
}

@RunWith(Parameterized.class) 
public class PalindromeServiceTest {

private final String checkedText; 
    private final boolean expected;

public boolean isPalindrome (String checkedText, boolean expected) { 
        this.checkedText = checkedText; 
        this.expected = expected; 
    }

@Parameterized.Parameters  
    public static Object[][] getTestData() {  
        return new Object[][] { 
            {&#34;anna&#34;, true}, 
            {&#34;anka&#34;, false}, 
            {&#34;q&#34;, true}, 
        }; 
    }

@Test  
    public void shouldCheckPalindrome() { 
        PalindromeService palindromeService = new PalindromeService(); 
        boolean actual = palindromeService.isPalindrome(checkedText); 
        assertEquals(expected, actual);  
    } 
}

Выдает ошибку 
1)cannot assign a value to final variable checkedText (this.checkedText = checkedText) 2)cannot assign a value to final variable expected  (this.expected = expected)
