### Question:
ByteFormat { public String format2(int count) { if (count < KILOBYTE) { return format(count); } synchronized (numberFormat) { return format(count) + " (" + numberFormat.format(count) + " bytes)"; } } ByteFormat(); String format(int count); String format2(int count); String format(long count); String format2(long count); void setMinimumFractionDigits(int d); void setMaximumFractionDigits(int d); void setNames(String[] names);  }### Answer:
@Test public void format2Test() { ByteFormat bf = new ByteFormat(); Assert.assertEquals("100 bytes", bf.format2(100)); Assert.assertEquals("999 bytes", bf.format2(999L)); Assert.assertEquals("9.8 KB (10,000 bytes)", bf.format2(10000)); Assert.assertEquals("97.7 KB (99,999 bytes)", bf.format2(99999L)); }
