Q. Question of ch. 11 of textbook:-1,2,3,4,9

IP Q:1Create a Java Desktop Application to find the Discount of an item on the basis of

Category

of item[Electrical Appliance/Electronic Gadget / Stationary ].The Categories will be

implemented in JRadioButton controls. The Discount will be calculated as follows :

COST DISCOUNT(%)



Class - XI

Otherwise 10

The extra Discount will be calculated as follows :

CATEGORY DISCOUNT(%)

Electrical Appliance 3

Electrical Gadget 2

Stationary 1

Calculate the total discount as : Discount on cost +Discount on Category

Calculate the discount amount as : cost * discount

On clicking of Exit Button ,it will exit the application



Class - XI

Q:2 Read the following case study and answer the questions that follow.

TeachWell Public School wants to computerize the employee salary section.

The School is having two categories of employees : Teaching and Non Teaching. The Teaching

employees are further categorized into PGTs, TGTs and PRTs having different Basic salary.

The School gives addition pay of 3000 for employees who are working for more than 10 years.

Employee Type Basic Salary DA (% of Basic

Write the code to calculate the Basic salary, deductions, gross salary and net salary based on the given specification.

Add 3000 to net salary if employee is working for more than 10 years.

Gross salary=Basic salary + DA + HRA

Net salary = Gross salary deductions

Q:3 Write the code to clear all textfields, uncheck checkbox and set non teaching

as the default category.

Q:4Design the following application and answer the questions that follow :



Class - XI

(a) Write the code for the Clear button to clear all the textfields and checkbox. Set the default choice in the radio button as Fixed Deposit.

(b) Write the code for the calculate button to calculate compound interest and amount and display the values in the txtInterest and txtAmount depending on principal, rate and time. Rate is calculated based on the time according to the following table: Account

Q:5 ABC School uses the following interface built in java to check the eligibility of a student for a particular stream from science, commerce and humanities. The user first enters the total percentage and selects the desired stream by selecting the appropriate option button. An additional 5% is marks is given to students of NCC. Write Java Code for the following a. On Action event of the button 'Calc Percentage' Net percentage of the student is calculated and displayed in the appropriate text filed. Net percentage is same as that of the actual percentage if the student doesn't opts for NCC otherwise 5% is added to actual percentage. b. On Action event of the button 'Result', the application checks the eligibility of the students. And display result in the appropriate text field. Minimum percentage for science is 70, 60 for commerce and 40 for humanities.
