//NEX GUI
import javax.swing.JFrame;
public class NEX { extends JFrame
private static final int WIDTH =500;
private static final int HEIGHT =175;
public NEX()
{
setTitle("New Customer"); //sets the title of the frame
setSize(Width,Height);
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
JFrame aNEX =new NEX();
aNEX.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
aNEX.setVisible(true); //display the frame
// TODO code application logic here
}
}
最佳答案
编码
public class NEX {extends JFrame
应该
public class NEX extends JFrame {
因为您正在使用Java。
另外,正如乔普·艾格(Joop Eggen)指出的那样,代码
setSize(Width,Height);
应该为setSize(WIDTH,HEIGHT);
,因为在声明它们时使用了所有大写字母。
