Cannot scan the String or Integer

Question

So I'm trying to compute a Simple program that has an n number of objects of the type Person and each person has a name, id, passport and driving licence.

It goes like this:

public class Person {



    private String name;

    private int id;

    private int passport;

    private int licence;



    Person(String name, int id, int passport, int licence) {

        this.name=name;

        this.id=id;

        this.passport=passport;

        this.licence=licence;

    }

}



public class Main {

    public static void main(String[] args) {

        Scanner jin=new Scanner(System.in);

        int n=jin.nextInt(), i;

        Person[] dudes=new Person[n];

        for(i=0; i<n; i++) {

            String name=jin.nextLine();

            int id=jin.nextInt();

            int passport=jin.nextInt();

            int licence=jin.nextInt();

            dudes[i]=new Person(name, id, passport, licence);

        }

    }

}

However when I enter a value for the String name it gives me this error:

Exception in thread "main" java.util.InputMismatchException

at java.util.Scanner.throwFor(Unknown Source)

at java.util.Scanner.next(Unknown Source)

at java.util.Scanner.nextInt(Unknown Source)

at java.util.Scanner.nextInt(Unknown Source)

at test.Main.main(Main.java:20)

Any ideas?

If you change String name = jin.nextLine(); to String name = jin.next(); it works how you have it.

An easier way would be to clear the buffer after typing an int like so for first and last names.

for(i=0; i<n; i++)
    {
        jin.nextLine();  // add this to clear the input from before.
        String name=jin.nextLine();
        int id=jin.nextInt();
        int passport=jin.nextInt();
        int licence=jin.nextInt();

        dudes[i]=new Person(name, id, passport, licence);
    }
