esercise with input with scanner
public static void main(String[] args) {
// TODO code application logic here
int i1 = 0;
int i2 = 0;
Scanner x = new Scanner(System.in);
System.out.println(“Enter an input: “);
i1 = x.nextInt();
System.out.println(“Enter another input: “);
i2 = x.nextInt();
int sum = i1 + i2;
System.out.println(“The sum of the two numbers is: ” + sum);
