import java.io.*;
class
{public static void main(String args[])throws IOException
DataInputStream z = new DataInputStream(System.in);
int a,b;
a = Integer.parseInt(z.readLine());
b = Integer.parseInt(z.readLine());
System.out.println("Sum:" + a + b);
System.out.println("Product:" + a * b);
}
}

Save the program in a file :.java
