基于Java swing+MySQL實(shí)現(xiàn)學(xué)生信息管理系統(tǒng)：功能：1錄入學(xué)生基本信息的功能； 2查詢學(xué)生基本信息的功能； 3修改學(xué)生基本信息的功能 ；4刪除學(xué)生基本信息的功能 ；5顯示所有學(xué)生信息的功能；應(yīng)付一般課設(shè)足矣，分享給大家。

1.開發(fā)環(huán)境：jdk11+win10+mysql 8+IDEA

記得將數(shù)據(jù)庫(kù)與IDEA或者eclipse連接起來(lái)，并記得添加數(shù)據(jù)庫(kù)驅(qū)動(dòng)jar包

這兩個(gè)分別是添加jar包和idea連接mysql大家可以做一下參考

IDEA導(dǎo)入mysql數(shù)據(jù)庫(kù)驅(qū)動(dòng)_跟著太陽(yáng).的博客-CSDN博客https://blog.csdn.net/qq_54705917/article/details/123484397?spm=1001.2014.3001.5502IDEA連接mysql數(shù)據(jù)庫(kù)_跟著太陽(yáng).的博客-CSDN博客https://blog.csdn.net/qq_54705917/article/details/123484737?spm=1001.2014.3001.5502?

2.數(shù)據(jù)庫(kù)設(shè)計(jì)

?代碼：

庫(kù)：create database?student
表：create table stu(
stuId varchar(20),
stuName varchar(20),
stuSex varchar(20),
stuAge varchar(20),
stuJG varchar(20),
stuLX varchar(20),
stuBJ varchar(20)
);

3. 窗口及功能設(shè)計(jì)

(1).主函數(shù)

main.java

import javax.swing.*;public class main {public static void main(String[] args) {JFrame jf = new StuLogin();} }

(2).登錄界面（默認(rèn)的賬號(hào)密碼都為：admin）

StuLogin.java
