### Question:
ByteVector { final ByteVector put122(final int byteValue, final int shortValue1, final int shortValue2) { int currentLength = length; if (currentLength + 5 > data.length) { enlarge(5); } byte[] currentData = data; currentData[currentLength++] = (byte) byteValue; currentData[currentLength++] = (byte) (shortValue1 >>> 8); currentData[currentLength++] = (byte) shortValue1; currentData[currentLength++] = (byte) (shortValue2 >>> 8); currentData[currentLength++] = (byte) shortValue2; length = currentLength; return this; } ByteVector();  ByteVector(final int initialCapacity);   ByteVector(final byte[] data); ByteVector putByte(final int byteValue); ByteVector putShort(final int shortValue); ByteVector putInt(final int intValue); ByteVector putLong(final long longValue); ByteVector putUTF8(final String stringValue); ByteVector putByteArray(
      final byte[] byteArrayValue, final int byteOffset, final int byteLength);  }### Answer:
@Test public void testPut122() { ByteVector byteVector = new ByteVector(0); byteVector.put122(1, 0x0203, 0x0405); assertArrayEquals(new byte[] {1, 2, 3, 4, 5}, toArray(byteVector)); }
