question: public static CharSequence [ ] split ( CharSequence line , int delimiter ) { CharSequence [ ] tokens0 = split ( line , delimiter , N ) ; if ( tokens0 . length < N ) { return tokens0 ; } else { CharSequence [ ] tokens1 = split ( tokens0 [ N - 1 ] , delimiter ) ; CharSequence [ ] tokens2 = new CharSequence [ tokens0 . length + tokens1 . length - 1 ] ; System . arraycopy ( tokens0 , 0 , tokens2 , 0 , tokens0 . length - 1 ) ; System . arraycopy ( tokens1 , 0 , tokens2 , tokens0 . length - 1 , tokens1 . length ) ; return tokens2 ; } }
target:  Splits a CharSequence according to the delimiter character.
