I don't understand where have I mistaken in the program. I would appreciate any help.

Question

Program :

import java.util.Scanner;

public class Program
{
public static void main(String[] args)
{
Scanner input = new Scanner (System .in);
int a,b,c,ch;
System .out .println ("Enter the two numbers\n");
a = input.nextInt();
b = input.nextInt();
System .out.println ("Enter the operation to perform\n1.Addition\n2.Subtraction\n3.Multiplication\n4.Division\n");
ch=input.nextInt();
switch (ch)
{
case 1:
c=a+b;
System .out.println ("Addition of the two numbers is"+c);
break;
case 2:
c=a-b;
System .out.println ("Subtraction of the two numbers is"+c);
break;
case 3:
c=a*b;
System .out.println ("Multiplication of the two numbers is"+c);
break;
case 4:
c=a/b;
System .out.println ("Division of the two numbers is"+c);
break;
default:
System .out.println ("Maybe you have entered a wrong choice\nSorry, but we can't process you request\n");
}
System .out.println ("Thank you for watching my program. Hope you liked it! ");
}
}

Answer 1

The playground has issues with white spaces for some reason. Causes an error when normally it shouldn't. Can go through and remove all your extra spaces between words and parenthesis, and words and periods.
