英文:
Compile Error cannot find symbol new Dashboard(); ^ symbol: class Dashboard location: class Main 1
问题
所以我尝试编译这个程序，但我一直收到错误消息
Main.java:39: 错误: 无法找到符号
new Dashboard();
^
符号: 类 Dashboard
位置: 类 Main
1 错误
我尝试查看其他类似的帖子，尝试了他们正在做的事情，但对我都不起作用。所以我想重新安装我的Java安装程序会起作用（从jdk7升级到jdk13），但我得到了相同的结果。我觉得自己很愚蠢，要问的可能是一个非常容易忽视的问题，但我一无所知。帮助我
import javax.swing.;
import java.awt.;
import java.awt.event.*;
public class Main implements ActionListener {
private int clicks = 0;
private JLabel label = new JLabel("点击次数： 0 ");
private JFrame frame = new JFrame();
public void Dashboard() {JButton button = new JButton("点击我");button.addActionListener(this);JPanel panel = new JPanel();panel.setBorder(BorderFactory.createEmptyBorder(30, 30, 10, 30));panel.setLayout(new GridLayout(0, 1));panel.add(button);panel.add(label);frame.add(panel, BorderLayout.CENTER);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame.setTitle("GUI");frame.pack();frame.setVisible(true);}public void actionPerformed(ActionEvent e) {clicks++;label.setText("点击次数： " + clicks);}public static void main(String[] args) {new Main().Dashboard();}
}
<details><summary>英文:</summary>So I'm trying to compile this program but I keep getting the error
Main.java:39: error: cannot find symbol
new Dashboard();
^
symbol: class Dashboard
location: class Main
1 error
I've tried looking at other similar posts trying out what they're doing but none of that worked for me. So I figured reinstalling my java installation would work (from jdk7 to jdk13), but I got the same results. I feel so stupid to ask what is probably a very easy oversight but I'm clueless. help me
import javax.swing.;
import java.awt.;
import java.awt.event.*;
public class Main implements ActionListener {
private int clicks = 0;
private JLabel label = new JLabel("Number of clicks: 0 ");
private JFrame frame = new JFrame();
public void Dashboard() {JButton button = new JButton("Click Me");button.addActionListener(this);JPanel panel = new JPanel();panel.setBorder(BorderFactory.createEmptyBorder(30, 30, 10, 30));panel.setLayout(new GridLayout(0, 1));panel.add(button);panel.add(label);frame.add(panel, BorderLayout.CENTER);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame.setTitle("GUI");frame.pack();frame.setVisible(true);}public void actionPerformed(ActionEvent e) {clicks++;label.setText("Number of clicks: " + clicks);}public static void main(String[] args) {new Dashboard();}
}
