【Abstract】 ?A new method,periodclassification algorithm,to get a better graphic of Julia sets of complex mapping z-2+c was given. Comparing with other algorithms such as escape time algorithm and inverse function algorithm, the periodclassification algorithm provides a better understanding of the dynamics of the complex mapping z-2+c. A large numbers of Julia sets of z-2+c were exhibited by use of a computer. Periodbuds were classified and the difference of the Julia sets in deferent periodbuds was studied. The period of the Julia set can be found and also the topological structure of the Julia set can be predicted by observing the position of the periodbud. A conjecture that all the Julia sets with 2 or higher periods are connected is presented. The conjecture is proved by lots of computer experiments.
