Trying a basic code

Question

Hi, i want to ask if the below program is possible using basic codes. The program should only receive 3 integers, otherwise it puts off the example2.

Example1:
Input:
1
24
7
Output:
WOW!
This is great!

Example2:
Input:
2
mall
code
7
11
Output:
Ummm..
This is awkward;

Answer 1

Brianna it goes like this.
I would encourage you to continue with Java course cause the exception handling technique is available there.

// Using try...catch block

import java.util.Scanner;
public class Main
{
public static void main(String args[])
{
try
{
Scanner input = new Scanner(System.in);
int number1= input.nextInt();
int number2= input.nextInt();
int number3= input.nextInt();

if( number1 == 1 && number2 == 24 && number3 == 7 )
{
System.out.println("WOW!");
System.out.println("This is great!");
}
else
{
System.out.println("Ummm...");
System.out.println("This is awkward");
}
}
catch( Exception ex )
{
System.out.println("Ummm...");
System.out.println("This is awkward");
}
}
}

People can write comments in our codes, we can also write comments in others' codes. But those comments are only accessible when using SoloLearn app. I'm guessing you are accessing SoloLearn from the web?

Answer 3

What should happen when:
1. No input was at all even provided.
2. When all input were non numeric, e.g. String.

I notice an inconsistency here, in the post "WOW This is great" is displayed when input were (1, 24, 7). But in your code you used a condition that requires inputb(1, 14, 7) for getting such output. Which one is correct?

I'd probably use exception handling (try...catch) block while reading the 3 integers to know whether `nextInt()` succeeded to get an `int` value (or not). This way we can count how many times we read input, and how many times we read numeric input (integral).

Answer 4

I wrote a sample code in your code, check the comments.

Answer 5

Okay 👌
So ... have you tried to use exception handling as I suggested?
How did it go?

Answer 6

Thank you so much!

Answer 7

No problem 👌

Answer 8

Ipang

Oh, I meant 24.
The program should only receive these two inputs given in example1 and example2.

Answer 9

Ipang , I haven't tried that yet so I'm having a problem.

Answer 10

Ipang

I may sound stupid, but where can I see the comments?

Answer 11

Yes, i dont have an app.
But I think you can send me a link, just write comments on the code

Answer 12

Hi
I want to know when ever I code it shows error in main() I don't know why can anyone help me I am a new user of this app

Answer 13

Aman Hi,
You must make a new thread for your own. Don't post question in other people's thread.

Follow the guides helow, and don't forget to include link to the troubling code, for analysis.
