very simple question about naming objects

I have a class called Tenant and I loop over the creation of 10 of
these objects. But I want to name them
Tenant1
Tenant2
Tenant3 etc

How do I do that?

In the code here they are all being named tenant rather than tenant1
etc:

for (int i=0; i<10; i++) {
Tenant tenant = new Tenant(i);
}

I thought maybe converting the int to a string like

Integer number = i;
String numberstring = number.toString();

But how would I then add numberstring onto the name of the object?

You don't. You use arrays.

Try:
Tenant[] tenants = new Tenant[10];
for (int i=0; i<10; i++) {
tenant[i] = new Tenant(i);
}

instead.

import java.util.SortedMap;
import java.util.TreeMap;

public class Tenants
{
public static void main(String[] args)
{
String prefix = "Tenant";
SortedMap<String, Tenant> tenants =
new TreeMap<String, Tenant>();
for(int i = 0; i < 6; i++)
{
String name =
prefix + Integer.valueOf(i).toString();
tenants.put(name, new Tenant(i));
}
for(String str : tenants.keySet())
{
System.out.println(str + " " + tenants.get(str).value);
}
}

static class Tenant
{
int value;
Tenant(int v){value = v;}
}
}
