我正在尝试构建一个生成地图的摇摆应用程序。

经过大量研究，我发现了 JXMapKit。

因此，我使用此处找到的 JXMapKit 库创建了一个应用程序：JXMapKit Libraries

基本上，当我运行我创建的程序时，我得到一个 java.lang.ArithmeticException: / 零错误，我不知道为什么。

这是我的代码：

主类：

import javax.swing.JFrame;

public class main {

  public static void main(String[] args) {
    frame f = new frame();
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setSize(500,500);
    f.setResizable(false);
    f.setLocationRelativeTo(null);
    f.setVisible(true);
  }
}

框架类：

import javax.swing.*;
import java.awt.BorderLayout;
import org.jdesktop.swingx.JXMapKit;

public class frame extends JFrame {

  JPanel panel;

  public frame(){
    super("Map Test");

    panel = new JPanel();
    panel.setLayout(new BorderLayout());
    add(panel);

    JXMapKit kit = new JXMapKit();
    kit.setDefaultProvider(JXMapKit.DefaultProviders.OpenStreetMaps);
    panel.add(kit, BorderLayout.CENTER);    
  }
}

这是所要求的整个堆栈跟踪，当我单击其中一行时，它说行号不存在：
