### Question:
Utilities extends Static { public static boolean equals(final float o1, final float o2) { return Float.floatToIntBits(o1) == Float.floatToIntBits(o2); } private  Utilities(); static boolean equals(final float o1, final float o2); static boolean equals(final double o1, final double o2); static int hash(final boolean value, final int seed); static int hash(final char value, final int seed); static int hash(final int value, final int seed); static int hash(final long value, final int seed); static int hash(final float value, final int seed); static int hash(final double value, final int seed); static int hash(final Object value, int seed); static boolean listNullEquals(List<?> l1, List<?> l2); static final Version VERSION; }### Answer:
@Test public void testEquals() { assertTrue (Utilities.equals(4.0, 4.0)); assertFalse(Utilities.equals(4.0, 4.1)); assertTrue (Utilities.equals(NaN, NaN)); }
