1-500,501-1000,1001-1500,每500个文件一个文件夹的算法

for(List<TCComponentDataset> allDataSetList : allDataSetsList) {
	for(int index=0;index<allDataSetList.size();index++) {
		int number = index + 1;
		waitingDialog.getContent().setText("共有"+dataSetSize+"个数据集需要导出，正在导出第"+number+"个数据集...");
		TCComponentDataset dataSetIndex = allDataSetList.get(index);
		String dataSetName = dataSetIndex.getProperty("object_name");
		int num = index / 500;
		String folderName = (1+(num*500)) + "-" + ((num+1) * 500);
		String folderPath = path + "\\"+folderName;
		File folderFile = new File(folderPath);
		if(!folderFile.exists()) {
			folderFile.mkdir();
		}
		String newFileName = folderPath + "\\" + dataSetName;
		File destFile = new File(newFileName);
		File srcFile = HFDatasetUtil.getInstance().getFile(dataSetIndex,errorSb);
		if(srcFile != null) {
			FileUtils.copyFile(srcFile, destFile);
		}
	}
}

　　核心代码：

for(int index=0;index<allDataSetList.size();index++) {
	int num = index / 500;
	String folderName = (1+(num*500)) + "-" + ((num+1) * 500);
	String folderPath = path + "\\"+folderName;
	if(!folderFile.exists()) {
		folderFile.mkdir();
	}
}
