### Question:
BooleanUtil { public static boolean isFalseOrNull(final Boolean b) { return b == null || !b; } private  BooleanUtil(); static boolean ifTrue(final Boolean bool, final Runnable runnable); static boolean isTrueOrNull(final Boolean b); static boolean isFalseOrNull(final Boolean b); static boolean isTrue(final Boolean b); static boolean isFalse(final Boolean b); static boolean isTrue(final String str);  }### Answer:
@Test public void testIsFalseOrNull() { assertTrue("null", BooleanUtil.isFalseOrNull(null)); assertFalse("Boolean.TRUE", BooleanUtil.isFalseOrNull(Boolean.TRUE)); assertFalse("true", BooleanUtil.isFalseOrNull(true)); assertTrue("Boolean.FALSE", BooleanUtil.isFalseOrNull(Boolean.FALSE)); assertTrue("false", BooleanUtil.isFalseOrNull(false)); }
