Answer 1

● U need to create only 1 Scanner object & use its .nextInt() method multiple times 👍[can use other methods also, but only 1 object in sufficient]

//here is corrected code :

import java.util.Scanner;
public class Program
{
static int min(int a,int b)
{
if(a>b)
{
return b;
}
else
{
return a;
}
}
public static void main(String[] args) {
int a;
int b;
Scanner der=new Scanner(System.in);
a=der.nextInt();
b=der.nextInt();
System.out.println(min(a,b));
}
}
