user input 2 numbers , add and print here in sl ?? java

Question

is there some problem with my system or more than one user input in java here at SL not allowed??

Answer 1

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
int i,j;
Scanner inp=new Scanner(System.in);
i=inp.nextInt();
j=inp.nextInt();
System.out.println(i+j);
}
}
Input should be in separate lines :
1
2
output:3

Answer 2

Multiple inputs can be collected by separating them with a new line.

Example (Code Playground):

1
2

Answer 3

ok i got it that in same input box we can input more than 1 value pressing enter each time

but how user will know about number of inputs??

public class Program
{
public static void main(String[] args) {

public class Program {
public static void main(String[] args) {
int i,j;
System.out.println("Enter two numbers to add:");
//this msg gets displayed with result

Scanner inp=new Scanner(System.in);
i=inp.nextInt();
j=inp.nextInt();

System.out.println(i+j);

}

}

}
}

//Input should be in separate lines :
1
2
output:3
