How to break out of an if statement mid way | java

I have an if statement (turn based attacks) if there an easy way to break out of the if statement so that the enemy doesn't attack back if it's already dead?

Hopefully without doing another if statement equal to the one I already have. Just sounds stupid to have 2 of the same if statements inside each other.

The simplest way would be for the While loop to break out as soon as the Enemy dies I guess. But I'm not the expert.

while (!monster.isDead() && !player.isDead())
        {
            HashSet<String> input = reader.getInput();

            if(input.contains("attack")) {
                int playerAttack = player.attack();
                int monsterAttack = monster.attack();

                if (monster.getMonsterLiv() > 0) 
                {                   
                    monster.getAttacked(playerAttack);                
                    System.out.println(Utilities.battleString(player.getName(), monster.getMonsterNavn(), playerAttack, monsterAttack, monster.getMonsterLiv()));
                    overView += "\n" + Utilities.battleString(player.getName(), monster.getMonsterNavn(), playerAttack, monsterAttack, monster.getMonsterLiv());

                    player.getAttacked(monster.attack()); 
                    System.out.println(Utilities.battleString(monster.getMonsterNavn(), player.getName(), monsterAttack, playerAttack, player.getHealth()));
                    overView += "\n" + Utilities.battleString(monster.getMonsterNavn(), player.getName(), monsterAttack, playerAttack, player.getHealth());
                } else {
                    monster.getAttacked(playerAttack);                
                    System.out.println(player.getName() + " attacks " + monster.getMonsterNavn() + " for " + playerAttack + " damage, and kills the " + monster.getMonsterNavn());
                    overView += "\n" + player.getName() + " attacks " + monster.getMonsterNavn() + " for " + playerAttack + " damage, and kills the " + monster.getMonsterNavn();
                }
            }
            else if (input.contains("run"))
            {
                player.setGold(player.getGold() - 50);
                break;
            }
            else {
                System.out.println("Unknown word, try \"attack\" or \"run\" instead!");
            }
        }

The way I've done this might be slightly weird. Any formatting tips for the code is also welcome!
