将java程序打包成“可执行”文件示例

package T;

import javax.swing.JOptionPane;
public class InputDialogDemo {
    /** Main method */
    public static void main(String[] args){
        // Prompt the user to enter a year 
        String yearString = JOptionPane.showInputDialog(null,"Enter a year", "Input (int)", JOptionPane.QUESTION_MESSAGE);
    }
}
