### Question:
NullColumn implements ReadOnlyColumn { @Override public byte getByte(long offset) { return 0; }  @Override void of(FilesFacade ff, LPSZ name, long pageSize, long size); @Override void close(); @Override BinarySequence getBin(long offset); @Override long getBinLen(long offset); @Override boolean getBool(long offset); @Override byte getByte(long offset); @Override double getDouble(long offset); @Override long getFd(); @Override float getFloat(long offset); @Override int getInt(long offset); @Override long getLong(long offset); @Override short getShort(long offset); @Override CharSequence getStr(long offset); @Override CharSequence getStr2(long offset); @Override char getChar(long offset); @Override int getStrLen(long offset); @Override void grow(long size); @Override void getLong256(long offset, CharSink sink); @Override Long256 getLong256A(long offset); @Override Long256 getLong256B(long offset); @Override boolean isDeleted(); @Override int getPageCount(); @Override long getPageSize(int pageIndex); @Override long getPageAddress(int pageIndex); static final NullColumn INSTANCE; }### Answer:
@Test public void getByte() { Assert.assertEquals(0, NullColumn.INSTANCE.getByte(1234)); }
