Again it's me (sorry if I ask too much, I'm new to this area) 🙂

The problem is that I cannot find the numbers I have entered and cannot print all the numbers in the menu. If you could help me it would be a big help 🙁

This is the exercise suggested by my teacher: c

Create a system that asks for the length of the array. This array contains whole cigars.
The following menu is available:

1.- Alta de un numero

The index of the next empty position is an attribute in the class in which the array is located.

2.- Busqueda de numero

The number is asked to search for it. If it is found, the positions where this number is located are displayed.

3.- Imprimir los numeros
4.- Salir

Note: The system has two classes, one of which is the main class and the other is the integer array.

This is my code:

1.- main class

import java.util.Scanner;

public class TestNumber {

public static void main(String() args) {
    Scanner leer = new Scanner(System.in);
    int opc, n, j = 0, l = 0, numeros = 0, dato;
    Numero num1;
    System.out.println("Ingrese el numero de arreglos, por favor: ");
    n = leer.nextInt();
    num1 = new Numero(n);
    do {
        System.out.println("1.- Alta de numero");
        System.out.println("2.- Busqueda de numero");
        System.out.println("3.- Imprimir numeros");
        System.out.println("4.- salir");
        opc = leer.nextInt();
        switch (opc) {
            case 1:
                if (j < n) {
                    j += 1;
                    System.out.println("Ingrese los numeros:");
                    numeros = leer.nextInt();
                    num1.setNumero(l, numeros);
                    System.out.println("Ingresando numeros.......");
                } else {
                    System.out.println("No puedes registrar más numeros");
                }
                break;
            case 2:
                System.out.println("Ingrese el numero que sea buscar");
                dato = leer.nextInt();
                    if (!num1.buscarNum(dato)) {
                    num1.buscarNum(dato);
                        System.out.println("El numero " + dato + " esta en la ubicación " + l);
                    } else {
                        System.out.println("No existe un numero en la ubicacion " + l);
                    }
                break;
            case 3:
                for (int i = 0; i < n; i++) {
                    System.out.println("Los numeros son: " + num1.getNum(i));
                }
                break;
        }
    } while (opc < 4);
}

}}

2.- number class

public class number {

private int numero();


Numero(int i) {
    numero = new int(i);
}

void setNumero(int i, int numeros) {
    numero(i) = numeros;
}

public boolean buscarNum(int dato) {
    for (int i = 0; i < numero.length; i++) {
        if (dato == numero(i)) {
            i = numero.length;
        }
        return true;
    }
    return false;
}

public int getNum(int i) {
    return numero(i);
}

}}
