List集合实现分页

public class ListPage {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();
        list.add("java");
        list.add("python");
        list.add("go");
        list.add("C");
        list.add("C++");
        list.add("VUE");
        int page = 2;
        int size = 3;
        list.forEach(
                a -> System.out.print(a + "\t")
        );
        System.out.println();
        List<String> pageList = handlePageList(list, page, size);
        pageList.forEach(
                b -> System.out.print(b + "\t")
        );
    }
    private static List<String> handlePageList(List<String> list, Integer currentPage, Integer pageSize) {
        List<String> currentPageList = new ArrayList<>();
        if (list != null && list.size() > 0) {
            int currIdx = (currentPage > 1 ? (currentPage - 1) * pageSize : 0);
            for (int i = 0; i < pageSize && i < list.size() - currIdx; i++) {
                String wordFrequencyDTO = list.get(currIdx + i);
                currentPageList.add(wordFrequencyDTO);
            }
        }
        return currentPageList;
    }
}
