This might be an easy answer but I'm new and my professor hasn't been much help, also feel free to correct my terminology. Essentially I have a class "Employee" and I'm trying to add several instances of it to an ArrayList to be printed later in Main. It looks kind of like this:

    public Employee(int id, String name, String bday, String gender, String job, int org)
{
    this.id = id;
    this.name = name;
    this.bday = bday;
    this.gender = gender;
    this.job = job;
    this.org = org;
}

All I really need to know how to do is print the values I've managed to assign to the constructor i.e. when I call a specific object from the ArrayList I'll be able to print the object's specific id, name, etc. I figured out that I can do it by creating a method for each individual variable but that would be really messy and inefficient, I'm looking for one method to call that would be able to do this.

Override Object.toString() in Employee. Something like,

@Override
public String toString() {
    return String.format("Employee id=%d, name=%s, bday=%s, gender=%s, job=%s, org=%s",
            id, name, bday, gender, job, org);
}

Then whenever you try and print it, the toString of Employee will be invoked.

System.out.println(new Employee(1, "Test", "A Birthday",
        "Yes", "Something", "Somewhere"));
