java print out class statement

Question

i am new to java and i have a simple question and i have this code

public abstract class Seq { int a, b, c;}

class For extends Seq{
public For( int first, int last, int step )
{
a=first;
b=last;
c=step;
}

and in the main i have:

For r1= new For(3, 4, 5);

what i want to do is that i want to add this statement in the main System.out.print(r1); and i want this statement to print "your parameters: 3, 4, 5"

how can i do this?

I would take a read through [How to use the toString method in Java?](http://stackoverflow.com/questions/3615721/how-to-use-the-tostring-method-in-java) — MadProgrammer, Nov 13 '12 at 04:42

Add a toString method in For as:

@Override
public String toString(){
    return "your parameters: "+ a + ", "+ b+ ", "+c;
}

You can do this by implementing the For class' toString method:

public String toString ( )
{
    return "your parameters: " + a + ", " + b + ", " + c;
}

You would have to override the toString() method and create another one that prints out the contents of r1.

@Override
public String toString(){
    return a + ", " + b + ", " + c;
}

Then it is simply:

System.out.println("Your parameters: " + r1.toString());
