public List<Student>list = new ArrayList<>(int page) {
	
	try {
		Class.forName("com.mysql.jdbc.Driver");
	} catch (ClassNotFoundException e1) {
		e1.printStackTrace();
	}
	
	try (Connection connection = DriverManager.getConnection(url, user, pass)) {
		int size =2;
		
		String sql = "SELECT * FROM student order by asc limit ?,?";
		java.sql.PreparedStatement statement = connection.prepareStatement(sql);

		int p = (page-1)*size;//分页id算法,用于计算开始id
		
		statement.setInt(1, p);
		statement.setInt(2,size);

	} catch (SQLException e) {
		e.printStackTrace();
	}
}
