我正在尝试构建一个生成地图的swing应用程序。
经过大量研究后，我找到了JXMapKit。
所以，我使用这里找到的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：/由零错误，我无法弄清楚原因。
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);
}
}
这是请求的整个堆栈跟踪，当我点击其中一行时，它表示行号不存在：
