Q1.
Write a program to find net pay where basic
salary taken as input.
da= 25%
of basic salary
ta= 2% basic
salary
pf= 15%
basic salary
gross
pay= basic salary+da+ta
net
pay=gross pay – pf
Solution:
import java.util.*;
//Start of clas Employee
public class Employee
{
public static void main(String args[])
{
//Local variables
double bs,da,ta,pf,gp,np;
Scanner sc=new Scanner(System.in);
System.out.println("Enter Basic salary:");
bs=sc.nextDouble();
da=bs*25.0/100.0;
ta=bs*2.0/100.0;
pf=bs*15.0/100.0;
gp=bs+da+ta;
np=gp-pf;
System.out.println("Gross payment:"+gp);
System.out.println("Net Payment :"+np);
}//end of main
}//end of class
Q2.
Write a program to input radius and find volume and surface area of a Sphere.
[ sa=4 π r2 v=4/3
π r3 ]
Solution
import java.util.*;
//Start of clas Sphere
public class Sphere
{
public static void main(String args[])
{
//Local variables
double v,sa,r,pi=314;
Scanner sc=new Scanner(System.in);
System.out.println("Enter Radius of Sphere:");
r=sc.nextDouble();
sa=4*pi*r*r;
v=(double)4/3*pi*r*r*r;
System.out.println("Surface area="+sa);
System.out.println("Volume
="+v);
}
}end of the class
Q3.
Write a program to accept a year and check whether the year is Leap year or
not. If the year in century then it is divisible by 400. If it is non-century
year then it is divisible by 4 but not 100.
Solution:
import java.util.*;
//Start of clas Leap Year
public class LeapYear
{
public static void main(String args[])
{
//Local variables
int year;
Scanner sc=new Scanner(System.in);
System.out.println("Enter year :");
year=sc.nextInt();
if ((year % 4 == 0) && year % 100 != 0)
{
System.out.println(year + " is a leap year.");
}
else if ((year % 4 == 0) && (year % 100 == 0) && (year %
400 == 0))
{
System.out.println(year + " is a leap year.");
}
else
{
System.out.println(year + " is not a leap year.");
}
}
} end of the class
