How can I get my program to run within a window in Java?

I am learning Java and figured that the best way to try and learn was to create a small text adventure that actually incorporates certain functions that I am actually trying to learn.

So, I have slowly been building my little game by trial and error and I am now at a stage where I would like to display it within an actual window and not within the IDE itself.

Here is the class which is called RoleGame:

package rolegame;

import java.util.*;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class RoleGame extends JFrame{


public static void main(String[] args){
    RoleGame RoleGameObject = new RoleGame();
    RoleGameObject.roleGame();

}



public void roleGame() {
    JPanel roleGame = new JPanel();
    add(roleGame);
    this.setSize(1000, 1000);
    // pack();
    setVisible(true);



    TheFellowship TheFellowshipObject = new TheFellowship();
    TheFellowshipObject.yourParty();
    System.out.println();
    FellowshipInventory FellowshipInventoryObject = new FellowshipInventory();
    FellowshipInventoryObject.inventory();
    FellowshipAttributes FellowshipAttributesObject = new FellowshipAttributes();
    FellowshipAttributesObject.characterAttributes();


    Scanner in = new Scanner(System.in);

    System.out.println();
    System.out.println("You face a horde of terrible orcs...\nWhat are you going to do?\n\nYour options are as follows:\n ");
    System.out.println("Roll a 1 to run...\nRoll a 2 to stand your ground...");
    System.out.println("Roll a 3 to attack...\nRoll a 4 to attack the leader...");
    System.out.println("Roll a 5 to have your whole party attack...\nRoll a 6 to kill them all...");
    System.out.println();
    System.out.print("Press return to roll the dice!!");
    in.nextLine();

    //System.out.println("You rolled a "+ num());
    for(int i = 0; i < 1; i++){
        int num = (int) (Math.random() * 6) + 1;
        System.out.println("You rolled a " + num + "\n");
    if(num == 1){
        System.out.println("You run away to fight another day when the odds are better...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.youRun();
    }
    else if(num == 2)
    {
        System.out.println("You stand your ground before the mighty horde...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.standGround();
    }
    else if(num == 3)
    {
        System.out.println("You run towards your foe screaming at them as you go...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.attack();
    }
    else if(num == 4)
    {
        System.out.println("You seek out the horde leader and make for him with your sword swinging...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.attackLeader();
    }
    else if(num == 5)
    {
        System.out.println("You rally your party by shouting for their assistance to slain the horde...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.rally();
    }
    else if(num == 6)
    {
        System.out.println("You and your party storm the horde and slain them all and cry    victory...!!");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.killThem();
    }
    Fighting FightingObject = new Fighting();
    FightingObject.fight();

    }

  }

}

First of all, please accept my apologies for the primitive code. I am sure you can appreciate that we all start at the bottom and this is a large learning curve for someone learning Java.

I have a couple of small issues with my code at the moment but I would really like to see it within its own window and then correct my other errors after.

Many thanks.

Solution

You first have to build an executable *. jar file. Doing that depends from the IDE, for example this is in Eclipse:

http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftasks-33.htm

In Netbeans: http://www.wikihow.com/Generate-JAR-File-in-Netbeans

And you can run the jar file in the command line using:

java -jar <your_jar_file>.jar

You can also generate an exe file out of that, but that is a topic on its own.
