Thread: Homework problem (scanner problems)

I'm supposed to create a program that Asks for 3 names, as well as their age. It should ask one name, then their age, then the next and so on. When I compile this program, here is what happens.

Enter the persons name:
Tom
Enter the persons age
20
Enter the persons name:
Enter the persons age
Tom
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 Oldest.main(Oldest.java:17)

Enter name shows up, I enter the name, enter age shows up, I enter the age, then the next set comes up together (Enter name, Enter age, without giving me a chance to enter a name before enter age pops up). The rest is the error message

import java.util.*;
public class Oldest {
public static void main(String[] args) {
	Scanner stdin = new Scanner(System.in);
	String per1name, per2name, per3name;
	int per1age, per2age, per3age;
 
	System.out.println("Enter the persons name: ");
	per1name = stdin.nextLine();
	System.out.println("Enter the persons age");
	per1age = stdin.nextInt();
	System.out.println("Enter the persons name: ");
	per2name = stdin.nextLine();
	System.out.println("Enter the persons age");
	per2age = stdin.nextInt();
	System.out.println("Enter the persons name: ");
	per3name = stdin.nextLine();
	System.out.println("Enter the persons age");
	per3age = stdin.nextInt();
 
	if((per1age > per2age) && (per1age > per3age)){
		System.out.println(per1name + " is the oldest person with the age " + per1age);
	}else if((per2age > per1age) && (per2age > per3age)){
		System.out.println(per2name + " is the oldest person with the age " + per2age);
	}else
		System.out.println(per3name + " is the oldest person with the age " + per3age);
}
}

Awesome that worked. Thanks for the fast reply!
