How to create an executable file in Java NetBeans?

1. First, you must click on the hammer+broom button (Clean and Build project)
2. The dist folder to be automatically generated after that.
3. In the dist folder, you can see Jar (Executable jar File). 
4. Jar File is actually an executable file.
5. *You can run this file through your Command Prompt program in your Windows. 

*To run the project from the command line, go to the dist folder and type the following:

java -jar "xxx.jar" 

If you are using Swing or AWT (fully GUI not the console), you can double-click on the Jar file to run your application!
Warning: If you choose GUI (Jar), you must add Swing Layout Extensions library to your Libraries trunk.

Enjoy!


Code : Tuto1.java  (Main)

package tuto1;

import java.util.Scanner; //console input
import javax.swing.JOptionPane; //dialog (input or output)

public class Tuto1 {

    public static void main(String[] args) {
      
      /*
        console input:-
        Scanner user_input = new Scanner(System.in);
      */
      String userName;
      userName = JOptionPane.showInputDialog("Name?"); //dialog
        
      /* Create two objects using constructor */
      Employee empOne = new Employee(userName);
      Employee empTwo = new Employee("Mary Anne");

      // Invoking methods for each object created
      empOne.empAge(26);
      empOne.empDesignation("Senior Software Engineer");
      empOne.empSalary(1000);
      empOne.printEmployee();

      empTwo.empAge(21);
      empTwo.empDesignation("Software Engineer");
      empTwo.empSalary(500);
      empTwo.printEmployee();
    }
}


Code : Employee.java

package tuto1;

public class Employee {
   String name;
   int age;
   String designation;
   double salary;

   // This is the constructor of the class Employee
   public Employee(String name){
      this.name = name;
   }
   // Assign the age of the Employee  to the variable age.
   public void empAge(int empAge){
      age =  empAge;
   }
   /* Assign the designation to the variable designation.*/
   public void empDesignation(String empDesig){
      designation = empDesig;
   }
   /* Assign the salary to the variable salary.*/
   public void empSalary(double empSalary){
      salary = empSalary;
   }
   /* Print the Employee details */
   public void printEmployee(){
      System.out.println("Name:"+ name );
      System.out.println("Age:" + age );
      System.out.println("Designation:" + designation );
      System.out.println("Salary:" + salary);
