Scanner type problem

[stoic light]

I am new to java and I am trying to do a code where I use scanner to have all my variables been put by the user. The problem is that when i need to put different types as input, the string i print to ask for different types print together and they take the same input in nextInt() or nextString(); it gives me a error because they are a different types. How can i make them to "wait" for their turn?

package ese_9;
import java.util.Scanner;
import java.util.ArrayList;

public class main {

    public static void main(String[] args) {
            Scanner input = new Scanner(System.in);
            System.out.println("Quanti clienti si vuole aggiungere?");
            int j=input.nextInt();

            new ArrayList<Cliente>();
            ArrayList<Cliente> gente= new ArrayList<Cliente>();
            for (int i=0; i <j;i++ ) {
            System.out.println("Inserire nome cliente: ");
            String nome= input.nextLine();
            System.out.println("Inserire identificativo del cliente: ");
            int id=input.nextInt();
            System.out.println("Inserire il numero di conto bancario del cliente: ");
            int idconto=input.nextInt();
            System.out.println("Inserire il saldo iniziale del cliente: ");
            double saldo=input.nextDouble();
            

            gente.add(new Cliente(nome, id));
            }
            System.out.println(gente);
    }

}

i will put the class Cliente just to understand better

package ese_9;

public class Cliente {
    private String nome;
    private int id;
    public Cliente(String nome,int i) {
        this.nome=nome;
        this.id=i;
    }
    
    public String getNome() {
        return nome;
    }
    
    public int getid() {
        return id;
    }
}

You could use next() rather than nextLine(). The data model involved makes it so mixing nextLine() with any other next()-like method produces confusion

Using next() rather than nextLine() is the easy fix. However, realistically, users can't type in anything but lines in the console. So the only way to truly react to what the other does, is to use nothing but nextLine(). The other methods corrupt the reality of the exchange

Thank you for the answer. If I always use nextLine(), then i would need to always declare the variable as string and then change it.
I was reading my teacher notes where she uses nextLine() and nextDouble() like i do, and it worked on her computer 😦

I haven't seen her code, but sometimes teachers aren't great examples.
You could obtain nothing but Strings with nextLine(), but nothing prevents you from converting whatever String you get to the type you want.

okay, thank you so much
