java项目管理系统(oak project)

Java项目管理系统（Oak Project）是一个基于Java语言开发的项目管理工具，它能够为项目组带来高效的项目管理体验。它采用的是开源的方式进行开发和维护，因此具有较好的可定制性和易扩展性。

Oak Project支持对项目进度的跟踪和分析，可以依据特定的指标对项目进行监控和评估。同时，Oak Project还支持协作工作，团队成员能够对项目任务进行分工、协作和反馈，提高诸如协作开发、任务分配等项目管理工作的效率。

Oak Project的另一个亮点是其功能的可扩展性。它可以通过插件机制来增强和补足其本身的功能缺陷，从而满足不同项目的需求。同时，还支持多国语言的本地化，可以大大方便全球范围内的使用。

总的来说，Oak Project是一个出色的项目管理工具，它使得项目管理变得更加容易和高效，是企业和个人确保项目进展的利器之一。

java图书馆管理系统mysql代码

很抱歉，我无法提供完整的图书馆管理系统的MySQL代码。但是，我可以给您一些参考：

1. 创建数据库和表

CREATE DATABASE library;

USE library;

CREATE TABLE books (
  book_id INT(11) NOT NULL AUTO_INCREMENT,
  title VARCHAR(255) NOT NULL,
  author VARCHAR(255) NOT NULL,
  category VARCHAR(255) NOT NULL,
  publisher VARCHAR(255) NOT NULL,
  publish_date DATE NOT NULL,
  price DECIMAL(10,2) NOT NULL,
  PRIMARY KEY (book_id)
);

CREATE TABLE members (
  member_id INT(11) NOT NULL AUTO_INCREMENT,
  name VARCHAR(255) NOT NULL,
  address VARCHAR(255) NOT NULL,
  phone VARCHAR(20) NOT NULL,
  PRIMARY KEY (member_id)
);

CREATE TABLE loans (
  loan_id INT(11) NOT NULL AUTO_INCREMENT,
  book_id INT(11) NOT NULL,
  member_id INT(11) NOT NULL,
  loan_date DATE NOT NULL,
  due_date DATE NOT NULL,
  return_date DATE,
  PRIMARY KEY (loan_id),
  FOREIGN KEY (book_id) REFERENCES books (book_id),
  FOREIGN KEY (member_id) REFERENCES members (member_id)
);

2. 插入数据

INSERT INTO books (title, author, category, publisher, publish_date, price) VALUES
('Head First Java', 'Kathy Sierra, Bert Bates', 'Programming', 'O''Reilly Media', '2003-02-09', 39.99),
('Thinking in Java', 'Bruce Eckel', 'Programming', 'Prentice Hall', '2006-02-20', 49.99),
('Java Concurrency in Practice', 'Brian Goetz, Tim Peierls, Joshua Bloch, Joseph Bowbeer, David Holmes, Doug Lea', 'Programming', 'Addison-Wesley Professional', '2006-05-19', 44.99),
('Effective Java', 'Joshua Bloch', 'Programming', 'Addison-Wesley Professional', '2008-05-08', 37.99);

INSERT INTO members (name, address, phone) VALUES
('John Smith', '123 Main St, Anytown, USA', '555-1234'),
('Jane Doe', '456 Oak St, Anytown, USA', '555-5678');

INSERT INTO loans (book_id, member_id, loan_date, due_date) VALUES
(1, 1, '2021-01-01', '2021-02-01'),
(2, 1, '2021-01-15', '2021-02-15'),
(3, 2, '2021-02-01', '2021-03-01');

3. 查询数据

-- 获取所有图书
SELECT * FROM books;

-- 获取所有借阅记录及其对应的图书和会员信息
SELECT loans.loan_id, loans.loan_date, loans.due_date, loans.return_date, books.title AS book_title, members.name AS member_name
FROM loans
INNER JOIN books ON loans.book_id = books.book_id
INNER JOIN members ON loans.member_id = members.member_id;

-- 获取某个会员的借阅记录及其对应的图书信息
SELECT loans.loan_id, loans.loan_date, loans.due_date, loans.return_date, books.title AS book_title
FROM loans
INNER JOIN books ON loans.book_id = books.book_id
WHERE loans.member_id = 1;

这些只是示例代码，具体的图书馆管理系统的代码会更复杂和详细。如有需要，您可以自行搜索相关资源或咨询专业人士。

用java和sql sever写一个学生信息管理系统

以下是一个简单的学生信息管理系统的Java代码和SQL Server数据库：

Java代码：

import java.sql.*;

public class StudentManagementSystem {
    
    // Establishing a database connection
    private static Connection getConnection() {
        Connection con = null;
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            String url = "jdbc:sqlserver://localhost:1433;databaseName=student_db";
            String username = "sa";
            String password = "password";
            con = DriverManager.getConnection(url, username, password);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return con;
    }
    
    // Adding a new student to the database
    public static void addStudent(String name, int age, String gender, String address, String phone) {
        try {
            Connection con = getConnection();
            PreparedStatement ps = con.prepareStatement("insert into students(name, age, gender, address, phone) values(?,?,?,?,?)");
            ps.setString(1, name);
            ps.setInt(2, age);
            ps.setString(3, gender);
            ps.setString(4, address);
            ps.setString(5, phone);
            ps.executeUpdate();
            System.out.println("Student added successfully!");
            con.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    // Updating an existing student in the database
    public static void updateStudent(int id, String name, int age, String gender, String address, String phone) {
        try {
            Connection con = getConnection();
            PreparedStatement ps = con.prepareStatement("update students set name=?, age=?, gender=?, address=?, phone=? where id=?");
            ps.setString(1, name);
            ps.setInt(2, age);
            ps.setString(3, gender);
            ps.setString(4, address);
            ps.setString(5, phone);
            ps.setInt(6, id);
            ps.executeUpdate();
            System.out.println("Student updated successfully!");
            con.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    // Deleting a student from the database
    public static void deleteStudent(int id) {
        try {
            Connection con = getConnection();
            PreparedStatement ps = con.prepareStatement("delete from students where id=?");
            ps.setInt(1, id);
            ps.executeUpdate();
            System.out.println("Student deleted successfully!");
            con.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    // Displaying all students in the database
    public static void viewStudents() {
        try {
            Connection con = getConnection();
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery("select * from students");
            while (rs.next()) {
                System.out.println("ID: " + rs.getInt("id"));
                System.out.println("Name: " + rs.getString("name"));
                System.out.println("Age: " + rs.getInt("age"));
                System.out.println("Gender: " + rs.getString("gender"));
                System.out.println("Address: " + rs.getString("address"));
                System.out.println("Phone: " + rs.getString("phone"));
                System.out.println();
            }
            con.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    // Main method to test the program
    public static void main(String[] args) {
        addStudent("John Doe", 20, "Male", "123 Main St", "555-1234");
        addStudent("Jane Smith", 21, "Female", "456 Oak Ave", "555-5678");
        viewStudents();
        updateStudent(1, "Johnny Doe", 21, "Male", "123 Main St", "555-1234");
        deleteStudent(2);
        viewStudents();
    }
}

SQL Server数据库：

create database student_db;

use student_db;

create table students(
    id int primary key identity(1,1),
    name varchar(50) not null,
    age int not null,
    gender varchar(10) not null,
    address varchar(100) not null,
    phone varchar(20) not null
);

注意：这只是一个简单的示例程序，实际的学生信息管理系统需要更多的功能和完善的错误处理。同时，本程序的数据库连接信息（url、username、password）应该根据你的实际情况进行修改。
