I have programmed the game already, but now i need to figure out how to put it to a GUI.

This is my game code:

import java.util.Scanner; import java.util.Random; public class AdventureGame { public static void main(String[] args) { final int SHORT_SWORD_MIN = 1; final int SHORT_SWORD_MAX = 4; final int LONG_SWORD_MIN = 3; final int LONG_SWORD_MAX = 7; final int JUMP_KICK_MIN = 2; final int JUMP_KICK_MAX = 6; final int AXE_MIN = 2; final int AXE_MAX = 6; final int FIRE_BLAST_MIN = 4; final int FIRE_BLAST_MAX = 10; final int ROGUE_INIT_HP = 55; final int ROGUE_INIT_STRENGTH = 8; final int PALADIN_INIT_HP = 35; final int PALADIN_INIT_STRENGTH = 14; final int CHAN_INIT_HP = 45; final int CHAN_INIT_STRENGTH = 10; final int MINION_INIT_HP = 25; final int GOBLIN_INIT_STRENGTH = 4; final int SKELETON_INIT_STRENGTH = 3; final int WIZARD_INIT_HP = 40; final int WIZARD_INIT_STRENGTH = 8; final int NUM_GOBLINS = 3; final int NUM_SKELETONS = 5; String playerName = ""; int playerHP = 0, playerStrength = 0, playerDamageMin = 0, playerDamageMax = 0; String enemyName = ""; int enemyHP = 0, enemyStrength = 0, enemyDamageMin = 0, enemyDamageMax = 0; int characterChoice = 0, pathChoice = 0, itemChoice = 0, numEnemies = 0; String pathName = ""; int playerDamage, playerATK; int enemyDamage, enemyATK; int playerActionChoice, randomNumAnswer, randomNumGuess; Scanner keyboard = new Scanner(System.in); Random randomNums = new Random(); System.out.println(" Adventure Game - Start! "); System.out.println("Here are the characters:"); System.out.println("1. Rogue 2. Paladin 3. Jackie Chan "); System.out.print("Which character do you choose?: "); characterChoice = keyboard.nextInt(); switch(characterChoice) { case 1: playerName = "Rogue"; playerHP = ROGUE_INIT_HP; playerStrength = ROGUE_INIT_STRENGTH; playerDamageMin = SHORT_SWORD_MIN; playerDamageMax = SHORT_SWORD_MAX; break; case 2: playerName = "Paladin"; playerHP = PALADIN_INIT_HP; playerStrength = PALADIN_INIT_STRENGTH; playerDamageMin = LONG_SWORD_MIN; playerDamageMax = LONG_SWORD_MAX; break; case 3: playerName = "Jackie Chan"; playerHP = CHAN_INIT_HP; playerStrength = CHAN_INIT_STRENGTH; playerDamageMin = JUMP_KICK_MIN; playerDamageMax = JUMP_KICK_MAX; break; } System.out.printf(" You chose: %s ", playerName); System.out.print("The Evil Wizard must be defeated! He is in The Castle. To get to "); System.out.println("The Castle, you must travel through either:"); System.out.println("1. The Forest 2.

Time for battle! ", pathName, numEnemies, enemyName); for (int i = 1; i  0 && playerHP > 0) { playerDamage = randomNums.nextInt(playerDamageMax - playerDamageMin + 1) + playerDamageMin; playerATK = playerStrength + playerDamage; enemyHP -= playerATK; System.out.printf("%s attacks with ATK = %d + %d = %d ", playerName, playerStrength, playerDamage, playerATK); System.out.printf("%s HP is now %d - %d = %d ", enemyName, enemyHP + playerATK, playerATK, enemyHP); if (enemyHP  0) System.out.printf("%s defeated %s %d! ", playerName, enemyName, i); else { System.out.printf("--%s is defeated in battle!-- GAME OVER ", playerName); System.exit(0); } } // end of for loop System.out.printf("Your HP is: %d ", playerHP); System.out.println("Please choose a reward. 1. Healing Potion 2. Ring of Strength "); System.out.print("Which item do you choose?: "); itemChoice = keyboard.nextInt(); switch(itemChoice) { case 1: System.out.println(" You chose: Healing Potion "); playerHP += 10; System.out.printf("Your HP has increased to %d + %d = %d! ", playerHP - 10, 10, playerHP); break; case 2: System.out.println(" You chose: Ring of Strength "); playerStrength += 5; System.out.printf("Your Strength has increased to %d + %d = %d! ", playerStrength - 5, 5, playerStrength); } System.out.println("You have now reached The Castle! Time to battle The Evil Wizard! "); enemyName = "Wizard"; enemyHP = WIZARD_INIT_HP; enemyStrength = WIZARD_INIT_STRENGTH; enemyDamageMin = FIRE_BLAST_MIN; enemyDamageMax = FIRE_BLAST_MAX; randomNumAnswer = randomNums.nextInt(6) + 1; System.out.printf("***%s vs The Evil Wizard*** ", playerName); while(playerHP > 0 && enemyHP > 0) { System.out.println("Choose your action: 1. Attack 2. Attempt Spell Cast "); System.out.print("What would you like to do: "); playerActionChoice = keyboard.nextInt(); switch(playerActionChoice) { case 1: playerDamage = randomNums.nextInt(playerDamageMax - playerDamageMin + 1) + playerDamageMin; playerATK = playerStrength + playerDamage; enemyHP -= playerATK; System.out.printf(" %s attacks with ATK = %d + %d = %d ", playerName, playerStrength, playerDamage, playerATK); System.out.printf("%s HP is now %d - %d = %d ", enemyName, enemyHP + playerATK, playerATK, enemyHP); break; case 2: System.out.print("Enter your guess: "); randomNumGuess = keyboard.nextInt(); if (randomNumGuess == randomNumAnswer) { System.out.println(" Correct! "); System.out.printf("The %s's spell is cast successfully! The Wizard's HP is now 0! ", playerName); enemyHP = 0; } else System.out.println(" Incorrect! The spell cast fails! "); break; } if (enemyHP  0) { System.out.printf("--%s wins the battle!-- ", playerName); System.out.println("You win! Congratulations!"); } else { System.out.printf("--%s is defeated in battle!-- GAME OVER ", playerName); } } // end of main } // end of class

This is the MessageBox Class file

In this assignment, you will write a GUI-based program that simulates battles between a player and an enemy. Your program wil allow the user to choose values for different settings of the battle, such as the characters and the weapons, as well as the number of enemies that the player will battle. After the settings are configured, the user may run a simulation and later view the results of the simulation that include the total number of enemies defeated. The Graphical User Interface The figure below shows the state of the GUI when the program begins. The GUI contains controls that allow the user to select the player character, the player's weapon, the enemy's character, the enemy's weapon, the number of enemies per round, and the number of rounds of battle; the buttons at the bottom allow the user to run the battle simulation or exit the program.
