### Question:
ByteArrayProvider implements ByteProvider { @Override public InputStream getInputStream(long index) throws IOException { assertValidIndex(index, true); return new ByteArrayInputStream(srcBytes, (int) index, srcBytes.length - (int) index); } ByteArrayProvider(byte[] bytes);  ByteArrayProvider(String name, byte[] bytes); @Override void close(); @Override File getFile(); @Override String getName(); @Override String getAbsolutePath(); @Override InputStream getInputStream(long index); @Override long length(); @Override boolean isValidIndex(long index); @Override byte readByte(long index); @Override byte[] readBytes(long index, long length);  }### Answer:
@Test public void testInputStream() throws IOException { ByteArrayProvider bap = bap(1, 2, 3, 4, 5, 6); InputStream is = bap.getInputStream(0); assertEquals(1, is.read()); assertEquals(2, is.read()); InputStream is2 = bap.getInputStream(4); assertEquals(5, is2.read()); assertEquals(6, is2.read()); assertEquals(-1, is2.read()); InputStream is3 = bap.getInputStream(6); assertEquals(-1, is3.read()); }
