### Question:
AndPredicate implements Predicate<T> { @Override public boolean test(T input) { for (Predicate<? super T> p : myPredicates) { if (!p.test(input)) { return false; } } return true; } AndPredicate(Collection<? extends Predicate<? super T>> predicates);  AndPredicate(Predicate<? super T> arg1, Predicate<? super T> arg2); @Override boolean test(T input);  }### Answer:
@Test public void test() { Assert.assertTrue(new AndPredicate<Void>(Collections.<Predicate<Object>>emptyList()).test(null)); Assert.assertTrue(new AndPredicate<Void>(Arrays.asList(TRUE_PREDICATE)).test(null)); Assert.assertFalse(new AndPredicate<Void>(Arrays.asList(FALSE_PREDICATE)).test(null)); Assert.assertTrue(new AndPredicate<Void>(Arrays.asList(TRUE_PREDICATE, TRUE_PREDICATE)).test(null)); Assert.assertFalse(new AndPredicate<Void>(Arrays.asList(FALSE_PREDICATE, TRUE_PREDICATE)).test(null)); Assert.assertFalse(new AndPredicate<Void>(Arrays.asList(TRUE_PREDICATE, FALSE_PREDICATE)).test(null)); Assert.assertTrue(new AndPredicate<Void>(Arrays.asList(TRUE_PREDICATE, TRUE_PREDICATE, TRUE_PREDICATE)).test(null)); Assert.assertFalse(new AndPredicate<Void>(Arrays.asList(TRUE_PREDICATE, TRUE_PREDICATE, FALSE_PREDICATE)).test(null)); Assert.assertFalse(new AndPredicate<Void>(Arrays.asList(FALSE_PREDICATE, TRUE_PREDICATE, TRUE_PREDICATE)).test(null)); Assert.assertFalse(new AndPredicate<Void>(Arrays.asList(TRUE_PREDICATE, FALSE_PREDICATE, TRUE_PREDICATE)).test(null)); }
