檢查一個數字的奇偶性

Question

要檢查兩個表達式是否為真，您需要使用 &&。 語法 expression1 && expression2 在這個問題中，你需要檢查傳遞的數字是否為正 AND even

我的代碼：

public static boolean check(int num) {
        boolean result = (num == 1 && num % 2 == 0);
        return result;
}

測試：

@Test
public void test() {
    assertFalse(LogicAnd.check(-1));
    assertFalse(LogicAnd.check(1));
    assertTrue(LogicAnd.check(2));
}

錯誤：

java.lang.AssertionError: 預期 [true] 但發現 [false]

請幫我糾正

完成任務。錯誤與num == 1有關。必須顯示num >= 1
