### Question:
DynamicByteBuffer { public DynamicByteBuffer putLongAt(int index, long v) { _checkForWriteAt(index, 8); _buf.putLong(index, v); return this; } DynamicByteBuffer();   DynamicByteBuffer(int capacity);  DynamicByteBuffer(byte[] bytes);   DynamicByteBuffer(byte[] bytes, int offset, int length);  DynamicByteBuffer(java.nio.ByteBuffer buf); java.nio.ByteBuffer getNioByteBuffer(); final DynamicByteBuffer setAutoExpand(boolean autoExpand); final boolean isAutoExpand(); final int arrayOffset(); final byte[] array(); static DynamicByteBuffer allocate(int capacity); static DynamicByteBuffer wrap(byte[] bytes); static DynamicByteBuffer wrap(byte[] bytes, int offset, int length); static DynamicByteBuffer wrap(java.nio.ByteBuffer in); ByteOrder order(); @Deprecated ByteOrder order(ByteOrder o); DynamicByteBuffer mark(); DynamicByteBuffer reset(); DynamicByteBuffer compact(); DynamicByteBuffer duplicate(); DynamicByteBuffer fill(int size); DynamicByteBuffer fillWith(byte b, int size); int indexOf(byte b); DynamicByteBuffer put(byte v); DynamicByteBuffer put(byte[] v, int offset, int length); DynamicByteBuffer putAt(int index, byte v); DynamicByteBuffer putUnsigned(int v); DynamicByteBuffer putUnsignedAt(int index, int v); DynamicByteBuffer putShort(short v); DynamicByteBuffer putShortAt(int index, short v); DynamicByteBuffer putUnsignedShort(int v); DynamicByteBuffer putUnsignedShortAt(int index, int v); DynamicByteBuffer putInt(int v); DynamicByteBuffer putIntAt(int index, int v); DynamicByteBuffer putUnsignedInt(long value); DynamicByteBuffer putUnsignedIntAt(int index, long value); DynamicByteBuffer putLong(long v); DynamicByteBuffer putLongAt(int index, long v); DynamicByteBuffer putString(String v, Charset cs); DynamicByteBuffer putPrefixedString(int fieldSize, String v, Charset cs); DynamicByteBuffer putBytes(byte[] b); DynamicByteBuffer putBytesAt(int index, byte[] b); DynamicByteBuffer putBuffer(DynamicByteBuffer v); DynamicByteBuffer putBufferAt(int index, DynamicByteBuffer v); byte get(); DynamicByteBuffer get(byte[] dst, int offset, int length); DynamicByteBuffer get(byte[] dst); byte getAt(int index); int getUnsigned(); int getUnsignedAt(int index); byte[] getBytes(int size); byte[] getBytesAt(int index, int size); short getShort(); short getShortAt(int index); int getUnsignedShort(); int getUnsignedShortAt(int index); int getUnsignedMediumInt(); int getInt(); int getIntAt(int index); long getUnsignedInt(); long getUnsignedIntAt(int index); long getLong(); long getLongAt(int index); String getPrefixedString(int fieldSize, Charset cs); String getString(Charset cs); DynamicByteBuffer slice(); DynamicByteBuffer flip(); DynamicByteBuffer rewind(); DynamicByteBuffer clear(); int remaining(); int capacity(); int position(); DynamicByteBuffer position(int position); int limit(); DynamicByteBuffer limit(int limit); boolean hasRemaining(); DynamicByteBuffer skip(int size); String getHexDump(); @Override String toString(); @Override boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test (expected = IndexOutOfBoundsException.class) public void testGetAndSetPutLongAtException2() { DynamicByteBuffer buf = new DynamicByteBuffer(); buf.putLongAt(129, 121L); }
