Minor help required!!

Question

Hi,

Please go through this code first:

https://code.sololearn.com/cBGTsjd8oLNF/?ref=app

i am wondering whether it is possible to just write something like

System.out.println(A) ;

instead of writing

System.out.println(A.attribute1 + A.attribute2 + ...) ;

to get the following output:

car bmw series 5

the thing is... i tried it, but i didnt get any output(from this particular println).

btw, i just started using sololearn yesterday, and i'm also pretty new to java programming.

thank you.

Answer 1

Yes, you just override the objects toString() method.

public String toString() {
return this.attr1 + " " + this.attr2 + " " + etc;
}

Answer 3

As ChaoticDawg said, you need to override the toString() method, and modify the code a little.
