求助！C:\AccpApp.java:1: 错误: 需要class, interface或enum Package accpedu; ^ 1 个错误

Package accpedu;
import java.awt.Toolkit;
import javax.Swing.SwingUtilities;
import javax.Swing.UIManager;
import java.awt.Dimension;
public class AccpApp {
boolean packFrame = false;
public AccpApp() {
LoginFrame frame = new LoginFrame();
if (packFrame){
frame.pack();
}else {
frame.validate();
}
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height){
frameSize.height = screenSize.height;
}
if (frameSize.width > screenSize.width){
frameSize.width = screenSize.width;
}
frame.setLocation((screenSize.width - frameSize.width) / 2,(screenSize.height - frameSize.height) / 2);
frame.setVisible(true);

}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());

}catch (Exception exception){
exception.printStackTrace();
}
new AccpApp();
}
});

}

}

C:\AccpApp.java
Package accpedu

package 小写
你加包了，在C盘下边建个文件夹叫accpedu，java文件放在这下边

你好！ Package accpedu; 第一个字母大写了。 仅代表个人观点，不喜勿喷，谢谢。
