This is the exact error message: I just want it to run

run:

Explanation / Answer

Hi

There is a compile time error in code. Package secion should be mentioned first in the code. I see ou imported Scanner class is in first place. The first section should be package.

I have modified the code. Please find the below updated code.

Addition.java

package addition;
import java.util.Scanner;/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
/**
*
* @author Hello
*/
public class Addition {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Scanner input= new Scanner (System.in);
int number1;
int number2;
int sum;
  
System.out.print("Enter first integer:");
number1=input.nextInt();
System.out.print("Enter second integer:");
number2=input.nextInt();
  
sum=number1+number2;
System.out.printf("sum is %d ", sum);
}
  
}

Output:

Enter first integer:2
Enter second integer:3
sum is 5
