question: public LongBuffer put ( long [ ] src , int srcOffset , int longCount ) { JTranscArrays . checkOffsetAndCount ( src . length , srcOffset , longCount ) ; if ( longCount > remaining ( ) ) { throw new BufferOverflowException ( ) ; } for ( int i = srcOffset ; i < srcOffset + longCount ; ++ i ) { put ( src [ i ] ) ; } return this ; }
target:  Writes longs from the given long array, starting from the specified offset, to the current position and increases the position by the number of longs written.
