String[] str1 = {"aaa","bbb","ccc"};String[] str2 = {"bbb","ddd"};String[] str3 = {"eee","fff"};//运算开始：Map isH = new HashMap();for(String s:str1){if(isH.get(s)==""){continue;}isH.put(s,"");}for(String s:str2){if(isH.get(s)==""){continue;}isH.put(s,"");}for(String s:str3){if(isH.get(s)==""){continue;}isH.put(s,"");}String[] toStr = (String[])isH.keySet().toArray();
