Java is a programming language for object oriented programs. It is high level programming language developed by Sun Microsystems. Java is used to create applications that can run on single computer. Static variable act as global variable in Java and can be shared among all objects. The non static variable is specific to instance object in which it is created.
Answer:
The definition of a class Telephone is given as
public class Telephone // class telephone
{
String number; // variable number of type string
static int quantity = 250;
// variable quantity of type int
static double total = 1565.92; // variable total of type double
}
Explanation:
Following is the description of Statement
- Create a class "Telephone" by using the keyword class.In that class we declared data member .
- We declared a variable "number" of type "string" which has no constructor.
- We declared a variable "quantity" of type "int" which is a static type variable. The static type variable retains the value during the program execution.
- We declared a variable "total" of type "double" which is a static type variable. The static type variable retain the value during the program execution .

Answer:
To check if the year comes under each 100th year, lets check if the remainder when dividing with 100 is 0 or not.
Similarly check for 400th year and multiple 0f 4. The following C program describes the function.
#include<stdio.h>
#include<stdbool.h>
bool is_leap_year(int year);
void main()
{
int y;
bool b;
printf("Enter the year in yyyy format: e.g. 1999 \n");
scanf("%d", &y); // taking the input year in yyyy format.
b= is_leap_year(y); //calling the function and returning the output to b
if(b==true)
{
printf("Thae given year is a leap year \n");
}
else
{
printf("The given year is not a leap year \n");
}
}
bool is_leap_year(int year)
{
if(year%100==0) //every 100th year
{
if(year%400==0) //every 400th year
{
return true;
}
else
{
return false;
}
}
if(year%4==0) //is a multiple of 4
{
return true;
}
else
{
return false;
}
}
