public static int find ( byte [ ] arra , int start , int limit , byte [ ] arrb ) { int k = start ; limit = limit - arrb . length + 1 ; int value = arrb [ 0 ] ; for ( ; k < limit ; k ++ ) { if ( arra [ k ] == value ) { if ( arrb . length == 1 ) { return k ; } if ( containsAt ( arra , k , arrb ) ) { return k ; } } } return - 1 ; }
Returns the index of the first occurence of arrb in arra . Or - 1 if not found .
