Question

The basic salary of employees is undergoing a revision. Define a class called Grade_ Revision with the following specifications:

Instance variables/Data members:
String name: to store name of the employee
int bas: to store basic salary
int expn: to consider the length of service as an experience
double inc: to store increment
double nbas: to store new basic salary (basic + increment)
Member Methods:
Grade_Revision(): constructor to initialize all data members
void accept(): to input name, basic and experience
void increment(): to calculate increment with the following specifications: 

Experience	Increment
Up to 3 years	₹ 1,000 + 10% of basic
3 years or more and up to 5 years	₹ 3,000 + 12% of basic
5 years or more and up to 10 years	₹ 5,000 + 15% of basic
10 years or more	₹ 8,000 + 20% of basic

void display(): to display all the details of an employee.

Write the main method to create an object of the class and call all the member methods. 

Answer 1

import java.util.*;
public classGrade_Revision
{String name;
int bas, expn; // basic, experience
double inc, nbas; // increment, new basic

Grade_Revision()
{ name = "";
bas = 0;
expn = 0;
inc = 0.0;
nbas = 0.;
}

void accept()
{Scanner sn = new Scanner(System.in);
System.out.println("Enter the name");
name = sn.nextLine();
System.out.println("Enter the basic");
bas = sn.nextInt();
System.out.println("Enter the experience");
expn = sn.nextInt();
increment(); // calling the increment() method
display(); // calling the display() method
}

void increment()
{if (expn <= 3)
inc = 1000 + bas * 10 / 100;
else if (expn > 3 && expn < 5)
inc = 3000 + bas * 12 / 100;
else if (expn > 5 && expn <= 10)
inc = 5000 + bas * 15 / 100;
else if (expn >= 10)
inc = 8000 + bas * 20 / 100;
}

void display()
{System.out.println("Name: " + name);
System.out.println("Experience: " + expn);
System.out.println("Basic: Rs. " + bas);
System.out.println("Increment: Rs. " + inc);
}

public static void main(String args[])
{Grade_Revision ob = new Grade_Revision();
ob.accept();
ob.increment();
ob.display();
}}
