question: public ByteColumn ( int nrows , int capacity , byte defaultValue ) { super ( byte . class , new Byte ( defaultValue ) ) ; if ( capacity < nrows ) { throw new IllegalArgumentException ( "Capacity value can not be less than the row count." ) ; } m_values = new byte [ capacity ] ; Arrays . fill ( m_values , defaultValue ) ; m_size = nrows ; }
target:  Create a new IntColumn.
