22,466,057 | Alright so this is simple enough.
I need to print out all the parameters of an object at a specific index. However, all of the objects are displaying the memory address. I know you have to override the toString method. But I'm not quite sure where.
Any help would be great!
Here is my Employee class code:

```
@Override
public String toString() {
return name + ", " + age + ", " + department;
}
``` | ```
class Employee {
@Override
public String toString() {
return String.format("[Employee name=%s, age=%d, department=%s]",
name, age, department);
}
}
```
Now just loop over the array of employees and just print the employee object as you already have. |
