The document describes a Java program to calculate parcel shipping charges based on weight. It begins with an initial charge of Rs. 15 for the first 1KG. Any additional weight is charged Rs. 8 for every 500g or fraction thereof. The program takes a weight in KGs as input, calculates the remaining weight after deducting 1KG, determines the charge for full 500g increments and any fractional part, and outputs the total charge.

1. 2 . A special two-digit number is such that when the sum of its digits is added to the product of
its digits , the result is equal to original number
Example : 59
5+9 = 14
5*9 = 45
45+14 = 59 Therefore , 59 is a special two digit number
Write a program in java to check whether a number is special two-digit number or not
Ans-
class Prog2
{
static void test(int num)//user inputs a two-digit number
{
int m = num;
int product = 1;
int sum = 0;
while(m>0)
{
int dig = m%10;
sum = sum+dig;
product = product*dig;
m/=10;
}
int finalsum = sum+product;
if(finalsum==num)
System.out.println(num+” is a special two digit number “);
else
System.out.println(num+ ” is not a special two digit number “);
}
}
