### Question:
Integers { public static long all(long l) { long c = Long.bitCount(l); return ~any(c ^ 64); } private  Integers(); static long negative(long l); static int negative(int i); static short netative(short s); static long min(long lhs, long rhs); static int min(int lhs, int rhs); static short min(short lhs, short rhs); static long max(long lhs, long rhs); static int max(int lhs, int rhs); static short max(short lhs, short rhs); static long any(long l); static int any(int i); static short any(short s); static long all(long l); static int all(int n); static short all(short s); static long cmp(long lhs, long rhs, long equal, long unequal); static int cmp(long lhs, long rhs, int equal, int unequal); static short cmp(long lhs, long rhs, short equal, short unequal);  }### Answer:
@Test public void testAll() { long i = ~this.i; Assert.assertEquals(i == -1 ? -1 : 0, Integers.all(i)); Assert.assertEquals(((int) i) == -1 ? -1 : 0, Integers.all((int) i)); Assert.assertEquals(((short) i) == -1 ? -1 : 0, Integers.all((short) i)); }
