These are the slogans:

Exercise 2: Survey Load Write a function that asks the user the rating of 6 different attractions of the park denominated: A1, A2, A3, A4 and A5. The ratings go from 1 to 10 (1 is terrible and 10 is excellent or unbeatable). The aspects are: • Degree of Fun: is the fun or boring attraction. • Quality of Attraction: Attraction includes features that highlight it: lights, colors, etc. • Justice of the price: it is the cost of entry to the fair attraction. • Attention of the employees: The personnel that is found in the attraction is friendly. Request the qualifications to user and then print the average rating of each of the different attractions.

  int quiz[]= new int[4], total[]= new int[6], fnl;

            for(int i=0; i<6; i++) {

                System.out.println("Atraccion A"+ (i+1) + ":");

                for (int x=0; x<4; x++) {
                    if (x == 0) {
                        System.out.println("•\tGrado de Diversión: es la atracción divertida o aburrida.");
                        quiz[x] = sc.nextInt();
                    } else if (x == 1) {
                        System.out.println("•\tCalidad de la Atracción: La atracción incluye características que la resaltan: luces, colores, etc.");
                        quiz[x] = sc.nextInt();
                    } else if (x == 2) {
                        System.out.println("•\tJusticia del precio: es el costo de entrada a la atracción justo.");
                        quiz[x] = sc.nextInt();
                    } else if (x == 3) {
                        System.out.println("•\tAtención de los empleados: El personal que se encuentra en la atracción es amigable.");
                        quiz[x] = sc.nextInt();
                    }

                }

                total[i] = quiz[i]+total[i];

            total[i]= total[i]/4;

The error occurs when you try to access the value with index 4 of the array quiz , since the array quiz has only up to index 3 (valid indexes 0,1,2,3).

The correction is to put the correct index handler x to quiz , and put it inside the second for.

int quiz[]= new int[4], total[]= new int[6], fnl;

for(int i=0; i<6; i++) {

    System.out.println("Atraccion A"+ (i+1) + ":");

    for (int x=0; x<4; x++) {
        if (x == 0) {
            System.out.println("•\tGrado de Diversión: es la atracción divertida o aburrida.");
            quiz[x] = sc.nextInt();
        } else if (x == 1) {
            System.out.println("•\tCalidad de la Atracción: La atracción incluye características que la resaltan: luces, colores, etc.");
            quiz[x] = sc.nextInt();
        } else if (x == 2) {
            System.out.println("•\tJusticia del precio: es el costo de entrada a la atracción justo.");
            quiz[x] = sc.nextInt();
        } else if (x == 3) {
            System.out.println("•\tAtención de los empleados: El personal que se encuentra en la atracción es amigable.");
            quiz[x] = sc.nextInt();
        }
        total[i] = quiz[x]+total[i];
    }

    total[i]= total[i]/4;
}
