如何在junit中的params中传递类？

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

import java.util.Arrays;
import java.util.Collection;

@RunWith(Parameterized.class)
public class MyClassTest {
    private int input;
    private int expected;

    public MyClassTest(int input, int expected) {
        this.input = input;
        this.expected = expected;
    }

    @Parameters
    public static Collection<Object[]> data() {
        return Arrays.asList(new Object[][]{
                {1, 2},
                {2, 4},
                {3, 6}
        });
    }

    @Test
    public void testMultiply() {
        MyClass myClass = new MyClass();
        int result = myClass.multiply(input);
        assertEquals(expected, result);
    }
}
