I'm making a text based adventure game to practice java for my robotics club, and my code keeps repeating after it states the enemy and it repeats whats above in the console. The whole code is under, it may be a simple syntax error but i can't find where or whats wrong with it.

package idk;
import java.util.Random;
import java.util.Scanner;
import java.util.Arrays;
/**

public class Idk{

/**

public static void main(String[] args) {

    // System objects
    Scanner in = new Scanner(System.in);
    Random rand = new Random();


    // Player variables
    int health = 200;
    int attackDmg = 50;
    int numHealthPots = 3;
    int healthPotionHealAmount = 45;
            //String enemy = [rand.nextInt(idk.enemies.enems.length
            boolean running = false;

    System.out.println("Welcome to the dungeon!");
