帮我写一个分页的java代码

好的，我可以回答这个问题。以下是一个简单的Java分页代码示例：

public class Pagination {
    private int pageSize; // 每页显示的记录数
    private int currentPage; // 当前页码
    private int totalRecords; // 总记录数

    public Pagination(int pageSize, int currentPage, int totalRecords) {
        this.pageSize = pageSize;
        this.currentPage = currentPage;
        this.totalRecords = totalRecords;
    }

    public int getPageSize() {
        return pageSize;
    }

    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    public int getCurrentPage() {
        return currentPage;
    }

    public void setCurrentPage(int currentPage) {
        this.currentPage = currentPage;
    }

    public int getTotalRecords() {
        return totalRecords;
    }

    public void setTotalRecords(int totalRecords) {
        this.totalRecords = totalRecords;
    }

    public int getTotalPages() {
        return (totalRecords + pageSize - 1) / pageSize;
    }

    public int getStartIndex() {
        return (currentPage - 1) * pageSize;
    }

    public int getEndIndex() {
        int endIndex = currentPage * pageSize - 1;
        return endIndex < totalRecords ? endIndex : totalRecords - 1;
    }
}

这个类可以用来计算分页相关的参数，例如总页数、起始记录索引、结束记录索引等。你可以根据自己的需求进行修改和扩展。
