java实现公司人事管理系统要求有GUI界面代码怎么写

实现公司人事管理系统需要使用 Java GUI 库，比如 JavaFX 或者 Swing 来实现。以下是一个简单的 JavaFX 代码示例：

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class HRManagementSystem extends Application {

    Stage window;
    Scene scene;
    Button button;

    @Override
    public void start(Stage primaryStage) throws Exception {
        window = primaryStage;
        window.setTitle("HR Management System");

        //Grid Layout
        GridPane grid = new GridPane();
        grid.setPadding(new Insets(10, 10, 10, 10));
        grid.setVgap(8);
        grid.setHgap(10);

        //Name Label
        Label nameLabel = new Label("Name:");
        GridPane.setConstraints(nameLabel, 0, 0);

        //Name Input
        TextField nameInput = new TextField();
        GridPane.setConstraints(nameInput, 1, 0);

        //Age Label
        Label ageLabel = new Label("Age:");
        GridPane.setConstraints(ageLabel, 0, 1);

        //Age Input
        TextField ageInput = new TextField();
        GridPane.setConstraints(ageInput, 1, 1);

        //Email Label
        Label emailLabel = new Label("Email:");
        GridPane.setConstraints(emailLabel, 0, 2);

        //Email Input
        TextField emailInput = new TextField();
        GridPane.setConstraints(emailInput, 1, 2);

        //Submit Button
        Button submitButton = new Button("Submit");
        GridPane.setConstraints(submitButton, 1, 3);

        grid.getChildren().addAll(nameLabel, nameInput, ageLabel, ageInput, emailLabel, emailInput, submitButton);

        scene = new Scene(grid, 300, 200);
        window.setScene(scene);
        window.show();
    }

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

这个代码示例演示了如何使用 GridPane 布局来创建一个简单的人事管理系统的用户界面。你可以根据你的需求，添加更多的组件和逻辑来完善这个系统。
