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;
    }
