I'm a newbie to Java, and haven't completed learned it yet. Still, I'm trying my best to solve as many problems as possible and get better.

So my query is, how can this program be fixed ??

The output is something like (https://i.stack.imgur.com/c4qCn.jpg)

Someone please correct this program, without removing the Scanner class.

I really tried to make this program run, but it just wasn't working. The values were always 0 or 0.0, no matter what I did....

Can someone also explain what went wrong here ??

Thank you in advance.🤗🤗

You'll need to use the ob instance to access a and b.

ob.a = sc.nextDouble();
ob.b = sc.nextDouble();
