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