    Default dont know how to describe the problem.

    The thing is, i'm making a little simple game, you hit a zombie and zombie hits you back. the thing is, the user have 2 attack types (normal and magic) and are controlled by the letters M and N (uppercase).

    i want to display a message if you type other letters besides N and M and i what to accept lowecase characters to by converting lower to upper.

    	System.out.println("Ataca !!!  (N para golpe normal, M para golpe Magico):");
    			input = myScanner.findWithinHorizon(".",0) .charAt(0);
    			attack = Character.toUpperCase(input);
    			System.out.println(attack);
     
    			if (attack != 'M' || attack != 'N'){
    				System.out.println("No entendi.");
    			}

    some of the instructions are in spanish, sorry. every thing works fine, except if you time lowercase m or n. the program displays the error message (no entendi) and continues the normal run.

    what should i do?

    i being reading about have for 2 days only, and have little knowledge, ill post the complete code of the game, that summarize almost all that i know about java.

    package heroVsZombie;
    import java.util.Scanner;
    import java.util.Random;
     
    public class arena {
     
    	public static void main(String[] args) {
     
    		Scanner myScanner = new Scanner(System.in);
    		Random myRandom = new Random();
    		int zombieLife = 130;
    		int heroLife = 120;
    		char attack;
    		int hit;
    		int zombieHit;
    		String Hero;
    		int Crit;
    		int zLuck = 8;
    		char again;
    		char input;
     
    		System.out.println("Cual es el nombre del Heroe?:");
    		Hero = myScanner.nextLine();
     
    		while (zombieLife >= 1 && heroLife >= 1) {
     
    			System.out.println("Ataca !!!  (N para golpe normal, M para golpe Magico):");
    			input = myScanner.findWithinHorizon(".",0) .charAt(0);
    			attack = Character.toUpperCase(input);
    			System.out.println(attack);
     
    			if (attack != 'M' || attack != 'N'){
    				System.out.println("No entendi.");
    			}
     
    			if (attack == 'M' || attack == 'N') {
    				Crit = myRandom.nextInt (10)+1;
    				if (Crit >= zLuck){
    				zombieHit = myRandom.nextInt (10)+18;
    				heroLife = heroLife - zombieHit;
    				System.out.println("Zombie do " + zombieHit + " Critical Damage");
    			} else {
    				zombieHit = myRandom.nextInt (10)+9;
    				heroLife = heroLife - zombieHit;
    				System.out.println("Zombie do " + zombieHit + " Normal Damage");
    			}
    			}
    			if(attack == 'N') {
    				hit = myRandom.nextInt (10)+5;
    				System.out.println("you do " + hit + " Damage");
     
    				zombieLife = zombieLife - hit;
    				System.out.println("El Zombie tiene " + zombieLife + " HP restantes.");
    				System.out.println(Hero + " tiene " + heroLife + " HP restantes.");
    			} 
     
    			if (attack == 'M'){
    				hit = myRandom.nextInt (50)+20;
    				System.out.println("you do " + hit + " Magic Damage");
    				zombieLife = zombieLife - hit;
    				System.out.println("El Zombie tiene " + zombieLife + " HP restantes.");
    				System.out.println(Hero + " tiene " + heroLife + " HP restantes.");
     
    			} 
     
     
     
    			if (zombieLife <= 0) {
    				System.out.println("El Zombie esta Murides, " + Hero + " le puso una chinga.");
     
    			}
     
    			if (heroLife <= 0) {
    				System.out.println(Hero + " esta Murides.");
     
    			}
     
     
     
     
    		}
     
    		System.out.println("El Fin");
     
     
     
     
    	}
     
    }

    Try using an AND, &&, instead of an OR, ||, in the if statement.

    Play again:
    Wrap your code in a while loop & ask the user if they want to play again. Whatever the input, that should be part of the condition in your while loop.
