Java获取Date类型-针对SQL语句

简便使用Date类型：

 import java.sql.Connection;
 import java.sql.DriverManager;
 import java.sql.PreparedStatement;
 import java.sql.ResultSet;
 import java.sql.SQLException;
 import java.sql.Statement;

 public class test2 {
     public static void main(String[] args) {

         do_test2_all();
     }    

     private static int do_test2_all()
     {

         try {

             Class.forName("");//空缺
             String url = ""; //空缺
             String userID = "";//空缺
             String passwd = "";//空缺
             Connection conn = DriverManager.getConnection(url, userID, passwd);

             java.util.Date date = new java.util.Date();
             long t = date.getTime();
             java.sql.Date sqlDate = new java.sql.Date(t);
             java.sql.Time sqlTime = new java.sql.Time(t);

             String sql = "";
             PreparedStatement pstmt = null;
             sql = "select * from student where date=? and id=? and name=?";
             pstmt = conn.prepareStatement(sql);
             pstmt.setDate(1, sqlDate.valueOf("2019-01-01"));
             pstmt.setInt(2, 1234);
             pstmt.setString(3, "test");
             pstmt.executeUpdate();    

             pstmt.close();
             conn.close();
             System.out.println("end");
         }
         catch(ClassNotFoundException e){
             System.out.println(e.getMessage());
         }
         catch(SQLException e){
             System.out.println(e.getMessage());
         }

         return 0;
     }
 }
