用Java写一个学生信息管理系统的界面的详细的代码

以下是一个基于JavaFX库编写的学生信息管理系统的详细代码示例：

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

import java.util.ArrayList;

public class StudentInfoGUI extends Application {

    private ArrayList<Student> studentList = new ArrayList<>(); // 存储学生信息的列表

    @Override
    public void start(Stage primaryStage) throws Exception {
        // 创建界面布局
        GridPane gridPane = new GridPane();
        gridPane.setPadding(new Insets(10, 10, 10, 10));
        gridPane.setVgap(10);
        gridPane.setHgap(10);

        // 添加控件
        Label nameLabel = new Label("姓名：");
        TextField nameField = new TextField();
        Label idLabel = new Label("学号：");
        TextField idField = new TextField();
        Label majorLabel = new Label("专业：");
        TextField majorField = new TextField();
        Label gradeLabel = new Label("年级：");
        TextField gradeField = new TextField();
        Label phoneLabel = new Label("电话：");
        TextField phoneField = new TextField();
        Button addButton = new Button("添加");
        Button deleteButton = new Button("删除");
        Button searchButton = new Button("查找");

        // 设置控件位置
        gridPane.add(nameLabel, 0, 0);
        gridPane.add(nameField, 1, 0);
        gridPane.add(idLabel, 0, 1);
        gridPane.add(idField, 1, 1);
        gridPane.add(majorLabel, 0, 2);
        gridPane.add(majorField, 1, 2);
        gridPane.add(gradeLabel, 0, 3);
        gridPane.add(gradeField, 1, 3);
        gridPane.add(phoneLabel, 0, 4);
        gridPane.add(phoneField, 1, 4);
        gridPane.add(addButton, 0, 5);
        gridPane.add(deleteButton, 1, 5);
        gridPane.add(searchButton, 2, 5);

        // 创建场景
        Scene scene = new Scene(gridPane, 500, 300);

        // 设置窗口标题
        primaryStage.setTitle("学生信息管理系统");

        // 设置窗口场景
        primaryStage.setScene(scene);

        // 显示窗口
        primaryStage.show();

        // 添加按钮的点击事件
        addButton.setOnAction(event -> {
            String name = nameField.getText();
            String id = idField.getText();
            String major = majorField.getText();
            String grade = gradeField.getText();
            String phone = phoneField.getText();
            if (name.isEmpty() || id.isEmpty() || major.isEmpty() || grade.isEmpty() || phone.isEmpty()) {
                showAlert("添加失败", "请填写完整信息！");
            } else {
                Student student = new Student(name, id, major, grade, phone);
                studentList.add(student);
                showAlert("添加成功", "学生信息已添加！");
                clearInput();
            }
        });

        // 删除按钮的点击事件
        deleteButton.setOnAction(event -> {
            String id = idField.getText();
            if (id.isEmpty()) {
                showAlert("删除失败", "请输入学号！");
            } else {
                boolean isDeleted = false;
                for (Student student : studentList) {
                    if (student.getId().equals(id)) {
                        studentList.remove(student);
                        showAlert("删除成功", "学生信息已删除！");
                        isDeleted = true;
                        break;
                    }
                }
                if (!isDeleted) {
                    showAlert("删除失败", "学号不存在！");
                }
                clearInput();
            }
        });

        // 查找按钮的点击事件
        searchButton.setOnAction(event -> {
            String id = idField.getText();
            if (id.isEmpty()) {
                showAlert("查找失败", "请输入学号！");
            } else {
                boolean isFound = false;
                for (Student student : studentList) {
                    if (student.getId().equals(id)) {
                        showAlert("查找成功", student.toString());
                        isFound = true;
                        break;
                    }
                }
                if (!isFound) {
                    showAlert("查找失败", "学号不存在！");
                }
                clearInput();
            }
        });
    }

    // 显示提示框
    private void showAlert(String title, String message) {
        Alert alert = new Alert(Alert.AlertType.INFORMATION);
        alert.setTitle(title);
        alert.setHeaderText(null);
        alert.setContentText(message);
        alert.showAndWait();
    }

    // 清空输入框
    private void clearInput() {
        nameField.clear();
        idField.clear();
        majorField.clear();
        gradeField.clear();
        phoneField.clear();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

// 学生类
class Student {
    private String name;
    private String id;
    private String major;
    private String grade;
    private String phone;

    public Student(String name, String id, String major, String grade, String phone) {
        this.name = name;
        this.id = id;
        this.major = major;
        this.grade = grade;
        this.phone = phone;
    }

    public String getName() {
        return name;
    }

    public String getId() {
        return id;
    }

    public String getMajor() {
        return major;
    }

    public String getGrade() {
        return grade;
    }

    public String getPhone() {
        return phone;
    }

    @Override
    public String toString() {
        return "姓名：" + name + "\n" +
                "学号：" + id + "\n" +
                "专业：" + major + "\n" +
                "年级：" + grade + "\n" +
                "电话：" + phone + "\n";
    }
}

这个代码实现了一个简单的带有添加、删除和查找功能的学生信息管理系统界面。界面中添加了姓名、学号、专业、年级和电话等输入框，用户可以通过填写这些信息来添加、删除和查找学生信息。你可以根据实际需求修改和完善这个代码。
