problem scan variable to add to arraylist

Question

Good morning, I'm learning Java, I had a problem and I don't know what the solution is... I want to add a certain amount of data (name, address, money) to an arraylist, I do a for loop for this and when executing the Variable reading is not done correctly. When I use nextLine to read variable 0, the program jumps to 1, so I don't enter the amount of information I want Now, when I use next() this doesn't happen, but when I want to enter a space-separated name as data, the same jump is done as if I were using nextLine... does anyone have any recommendations? arrays

my code is not finished since I can't go from here

public static void main(String\[\] args) {
    Scanner sc = new Scanner(System.in);
    List <Cliente> lista = new ArrayList<Cliente>(); //declaracion y asignacion del ArrayList
    Cliente clie = new Cliente();

    System.out.println("De la cantidad de cientes a ingresar: ");
    int n = sc.nextInt();
    
    for (int i = 0; i < n; i ++) {
        //lista.add(new Cliente("nico","ramos ",1,25000));
        System.out.println("Al cliente se le asigno un numero de cliente");
        clie.setCodigoCliente(i);
        System.out.println("Ingrese el nombre del cliente " +i);
        String nom;
        clie.setNombre(nom = sc.nextLine());
        System.out.println("Ingrese la direccion del cliente "+i);
        String direccion;
        clie.setDireccion(direccion = sc.nextLine());
    }
}

public class Cliente {

    int codCliente;
    String nombre;
    String direccion;
    double credito;

    public Cliente() { }

    public Cliente(String nombre, String direccion, double credito) {
        // this.codCliente = codCliente;
        this.nombre = nombre;
        this.direccion = direccion;
        this.credito = credito;
    }

    // Getters and setters omitted for brevity

}

Try this code:

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class ClientTest {

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);

    List<Cliente> lista = new ArrayList<Cliente>(); //declaracion y asignacion del ArrayList Cliente clie = new Cliente();
    System.out.println("Enter how many clients will be added:");
    int n = sc.nextInt(); // if you will type here '2 abc' then
//n will be '2' and nextLine will be ' abc' that's why 'sc = new Scanner(System.in)' is used to reset the scanner

    sc = new Scanner(System.in);
    for (int i = 0; i < n; i++) {

        Cliente cliente = new Cliente();
        cliente.setCodigoCliente(i);
        System.out.println("Enter number of client# " + i);
        cliente.setNombre(sc.nextLine());
        System.out.println("Enter direccion of client: " + i);
        cliente.setDireccion(sc.nextLine());
        lista.add(cliente);
    }
    System.out.println(lista);
}

}

class Cliente {

int codCliente;
String nombre;
String direccion;
double credito;

public Cliente() {

}

public Cliente(String nombre, String direccion, double credito) {
    // this.codCliente = codCliente;
    this.nombre = nombre;
    this.direccion = direccion;
    this.credito = credito;
}

@Override
public String toString() {
    return "Cliente{" +
            "codCliente=" + codCliente +
            ", nombre='" + nombre + '\'' +
            ", direccion='" + direccion + '\'' +
            ", credito=" + credito +
            '}';
}

public void setCodigoCliente(int codCliente) {
    this.codCliente = codCliente;
}

public void setNombre(String nombre) {
    this.nombre = nombre;
}

public void setDireccion(String direccion) {
    this.direccion = direccion;
}

public void setCredito(double credito) {
    this.credito = credito;
}

public int getCodCliente() {
    return codCliente;
}

public String getNombre() {
    return nombre;
}

public String getDireccion() {
    return direccion;
}

public double getCredito() {
    return credito;
}
}
