Java method that generates random numbers passed by instance variables

Question

I am working on making a text based game in Java, I am using a class and instance variables and I am trying to create a method that generates a random number based on the number that the instance variable max_attack has.

public class badPlayer 
{
    String description;
    int health;
    int award;
    int max_attack;

    public badPlayer(String description, int health, int award, int attack){            
        this.description=description;
        this.health = health;
        this.award = award;
        this.max_attack = attack;
    }

   Random rnd = new Random();

    public int maxAttack(){ 
        int rand_int1 = rnd.nextInt(max_attack);
        return rand_int1;   
    }   
}

public class troll extends badPlayer
{
    troll(int attack){
        super("troll", 100, 50, 100);
    } 
}

Output

troll1005089

I would like the method to create random numbers between 1 and 100.

Answer 1

Random r = new Random();
int low = 1;
int high = 100;
int result = r.nextInt(high-low) + low;

I am working on making a text based game in Java, I am using a class and instance variables and I am trying to create a method that generates a random number based on the number that the instance variable max_attack has.

public class badPlayer

        this.health = health;
        this.award = award;
        this.max_attack = attack;
    }

   Random rnd = new Random();

    public int maxAttack(){ 
        int rand_int1 = rnd.nextInt(max_attack);
        return rand_int1;   
    }   
}

public class troll extends badPlayer
{
    troll(int attack){
        super("troll", 100, 50, 100);
    } 
}

Output

troll1005089

I would like the method to create random numbers between 1 and 100.

Answer 3

int result = 1 + random.nextInt(100);
