java遍历数组并重新拼接数组里的元素

public ArrayList getinferfacelist(ArrayList<TaskNameList> taskNameLists) {        String interfaceName="";        String splitedWorkTable = "";        ArrayList interfaceNameList =new ArrayList();        //遍历获取作业名list里的每个作业名        for(TaskNameList taskNameList:taskNameLists){            splitedWorkTable = taskNameList.getTaskName();            System.out.println("作业名："+splitedWorkTable);            //接口名就是作业名去掉前缀SPT_GESSPSBC-STOR_INFO            String[] split = splitedWorkTable.split("_");            // 遍历int数组，得到拆分作业名的每一个元素            for (int x = 1; x < split.length; x++){                // 先判断该元素是否为最后一个                if (x == split.length - 1){                    // 就直接拼接元素                    interfaceName += split[x];                } else{                    // 就拼接元素和_                    interfaceName += split[x];                    //split[1] = split[1].replace("-", "_");                    interfaceName += "_";                }            }            interfaceNameList.add(interfaceName);        }        System.out.println(interfaceName);        return interfaceNameList;    }
