java基于xml文件学生信息管理系统

你好，你要的学生信息管理系统。（1） Student类import java.io.Serializable;/** * @author liuxe * @since JDK 1.7.0_79 */public class Student implements Serializable { private int stuId; private String name; private String major; private String sex; private String contactWay; public int getStuId() { return stuId; } public void setStuId(int stuId) { this.stuId = stuId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getMajor() { return major; } public void setMajor(String major) { this.major = major; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String getContactWay() { return contactWay; } public void setContactWay(String contactWay) { this.contactWay = contactWay; }}（2） StuMis类import java.io.*;import java.util.ArrayList;import java.util.List;/** * @author liuxe * @since JDK 1.7.0_79 */public class StuMis { public static List studentList = new ArrayList(); public static boolean add(Student student) { return studentList.add(student); } public static boolean remove(Student student) { return studentList.remove(student); } public static boolean update(Student student) { for (Student dto : studentList) { if (student.getStuId() == dto.getStuId()) { studentList.remove(dto); } } return studentList.add(student); } public static Student queryByStuId(int id) { for (Student dto : studentList) { if (id == dto.getStuId()) { return dto; } } return null; } public static List queryByName(String name) { List returnList = new ArrayList(); for (Student dto : studentList) { if (name.equals(dto.getName())) { returnList.add(dto); } } return returnList; } public static void saveToFile() { try { ObjectOutputStream oo = new ObjectOutputStream(new FileOutputStream( new File("." + File.separator + "student.dat"))); oo.writeObject(studentList); } catch (Exception ex) { ex.printStackTrace(); } } public static void readFromFile() { try { ObjectInputStream ois = new ObjectInputStream(new FileInputStream( new File("." + File.separator + "student.dat"))); studentList = (List) ois.readObject(); } catch (Exception ex) { ex.printStackTrace(); } }}（3）、StuMisTest类：主函数测试学生信息管理系统import java.util.List;/** * @author liuxe * @since JDK 1.7.0_79 */public class StuMisTest { public static void main(String[] args) { Student student = new Student(); student.setStuId(1); student.setName("AAA"); student.setMajor("AAAA"); student.setSex("A"); student.setContactWay("AA"); Student student2 = new Student(); student2.setStuId(2); student2.setName("BBB"); student2.setMajor("BBBB"); student2.setSex("B"); student2.setContactWay("BB"); Student student3 = new Student(); student3.setStuId(3); student3.setName("CCC"); student3.setMajor("CCCC"); student3.setSex("C"); student3.setContactWay("CC"); //A、 增加一个学生记录 StuMis.add(student); StuMis.add(student2); StuMis.add(student3); //B、 删除一个学生记录 StuMis.remove(student2); //C、 修改学生信息 student.setMajor("DDDD"); StuMis.update(student); //D、 根据学号查找学生 Student studentXX = StuMis.queryByStuId(3); //E、 根据姓名查找学生。。。 List studentOO = StuMis.queryByName("AAA"); //F、 将集合中所有学生信息存储到student.dat中。 StuMis.saveToFile(); //G、 再次运行系统时加载student.dat中的学生信息，后支持A~E基本操作。 StuMis.readFromFile(); }}
