As someone just now coming in for Java after learning some C# this stuff is wack. Tip: do some looking into how various scanner methods work on value types. Take special note of where it stops.

in python

a=int(input()) b=float(input()) c=str(input()) sum1=a+i sum2=d+b sum3=s+c print(sum1) print(sum2) print(sum3)

import java.util.Scanner;

public class Solution { public static void main(String[] args) { int i = 4; double d = 4.0; String s = "HackerRank ";

    Scanner scan = new Scanner(System.in);

    // Declare variables
    int i2;
    double d2;
    String s2;

    // Read inputs
    i2 = scan.nextInt();
    d2 = scan.nextDouble();
    scan.nextLine();      // consume leftover newline
    s2 = scan.nextLine();

    // Print results
    System.out.println(i + i2);
    System.out.printf("%.1f\n", d + d2);
    System.out.println(s + s2);

    scan.close();
}

}

agreed on confunsing wording

python3

if __name__ == '__main__':
    i = int(4)
    d = float(4.0)
    s = str('HackerRank')
    
    a = int(input().strip())
    b = float(input().strip())
    c = str(input().strip())
    
    print(i+a)
    print(b+d)
    print(s, c)

I don't know if it's just me but the wording was super confusing.
