### Question:
BoolLayout implements BooleanDataLayout<ByteDataBuffer> { static byte booleanToByte(boolean b) { return (byte)(b ? 0x1 : 0x0); }  @Override void writeBoolean(ByteDataBuffer buffer, boolean value, long index); @Override boolean readBoolean(ByteDataBuffer buffer, long index);  }### Answer:
@Test public void booleanToByteTest() { assertEquals((byte)1, BoolLayout.booleanToByte(true)); assertEquals((byte)0, BoolLayout.booleanToByte(false)); }
