Override the toString() method

Example

class Student {
    private String name;
    private String lastname;        

    @Override
    public String toString() {
        return this.name + " " + this.lastname;
    }
}

You should do the same with the attributes of your Student class and call the Student.toString() method each time you want to show its content

how do you know that there are variables `name` and `lastName`? – Blip May 02 '16 at 02:50
So edit your answer and clearly state in your answer that this is an example and explain why this would help – Blip May 02 '16 at 03:02
The word 'Example' over the code block is not enough? – Gumby brain specialist May 02 '16 at 03:34
add some explanation as why and how this is going to solve the problem mentioned – Blip May 02 '16 at 03:47
