To check that both expressions are true, you need to use &&. Syntax expression1 && expression2 In this problem, you need to check that the number passed is positive AND even
my code:
public static boolean check(int num) { boolean result = (num == 1 && num % 2 == 0); return result; }
test:
@Test public void test() { assertFalse(LogicAnd.check(-1)); assertFalse(LogicAnd.check(1)); assertTrue(LogicAnd.check(2)); }
error:
java.lang.AssertionError: expected [true] but found [false]
