Java How to read an array of inputs

Question

I have a do while loop that asks for 2 forms of input 3 times.

I thought about putting these inputs into 2 arrays to be output later, but it ain't working.

Here's my code for you to look at:

int i = 0;
do {
   System.out.print("Enter a name ");
   String name = scanner.nextLine();

   System.out.print("Enter age ");
   String age = input.nextLine();
   newAge = Integer.parseInt(age);
   i++;
} while (i <= 3);

I want to output the values as such:

Names are: Name1; Name2; Name3

But I want to add the 3 ages together to make a totalAge variable.

You "thought" about putting the inputs into arrays, but did you actually try writing code that did that? If so, please post the code you tried. — ajb, Jun 25 '16 at 15:49
You say you tried arrays, but there are none in your code. Show us the code you tried that isn't working. — takendarkk, Jun 25 '16 at 15:50
That's why I posted on here, I don't know how to get started. — user6512771, Jun 25 '16 at 15:52

You can declare two arrays for name and age inputs, or you can create a class that holds them both, call it Person or something like that and create an array of these.

class Person {
    public String name;
    public Integer age;
}

You don't need a do-while loop, it will look better with a for, or even better with enhanced for:

int personsAmount = 3;
Person[] persons = new Person[personsAmount];
for (Person person : persons) {
    person = new Person();

    System.out.print("Enter a name ");
    person.name = scanner.nextLine();

    System.out.print("Enter age ");
    person.age = Integer.parseInt(scanner.nextLine());
}

@Shank So you think a Java course or a tutorial would teach arrays before arbitrary classes? Would be funny. – Tom Jun 25 '16 at 16:00
Albeit I don't think that classes are confusing for newbies, this answer isn't working anyway. But it proofs that [Java uses pass-by-value](http://stackoverflow.com/questions/40480/is-java-pass-by-reference-or-pass-by-value). – Tom Jun 25 '16 at 16:07

int i = 0;
String[] name = new String[3];
int[] age = new int[3];
do {
   System.out.print("Enter a name ");
   name[i] = scanner.nextLine();

   System.out.print("Enter age ");
   age[i] = Integer.parseInteger(input.nextLine());
   ;
   i++;
} while (i <= 3);

pls let him try 1st – Shank Jun 25 '16 at 15:55
Thanks Shiro, how do I then reference these outside so that I can print each name and then add the 3 ages outside the do while loop? – user6512771 Jun 25 '16 at 16:06
For example: System.out.println("Name: " + name[0] + " Age: " + age[0]) – Shiro Jun 25 '16 at 16:09
