LABORATORY EXERCISES

FIRST PRELIMINARY PERIOD

GRADED EXERCISE #1

Using BufferedReader/JOptionPane Class and Simple Formula Creations

Duration: 1 week

1. Write a JAVA program that will input Employee Name, Rate per hour, No. of hours worked

and will compute the daily wage of an employee. If the number of hours worked exceeds

eight hours add 30% to each excess hours as overtime rate.Formula: Daily Wage = Rate per hour * No. of hours worked + OT pay

2. Create a JAVA program that will input a student name, course, student grade in quiz,

seatwork, laboratory exercises, assignment and prelim exam. Compute and output the PrelimGrade.

Prelim Grade = Quiz * 25% + Seatwork * 10% + lab. Exercise * 20% +

Assignment * 5% + Prelim Exam * 40%

3. Create a JAVA program that will input a value of measure in inches and output its equivalent

in measure feet. Conversion Factor: 12 inches = 1 foot

4. Create a JAVA program that will input an integer and output its square and cube;

Example: 52 = 25 53 = 125

Input an integer: 5 The square of a 5 is 25

The cube of 5 is 125

5. Create a JAVA program that will input the following data: Employee Number, Employee

LastName, Employee FirstName, Rate per hour, Number of Hours Worked. Compute and

ouput the Gross Pay, SSS Deduction, Tax Withhold, Total Deduction, Net PayGross Pay = No. of hrs worked * rate per hour.

SSS Deduction = 5% of Gross Pay

Tax Withhold = 10% of Gross Pay

Total Deduction = SSS Deduction + Tax WithholdNet Pay = Gross Pay Total Deductions

GRADED EXERCISE #3Conditional Statements: If Else and Switch Case

Duration: 1 week

1. Write a JAVA program that will input the following data: Student Name, Average, Tuition Fee and

output Total Tuition Fee.

If average is: 95 100 100% discount

90 94 25%

85 89 10%84 and below no discount

2 Write a JAVA program that will input Employee Name, Rate per

hour, No. of hours worked and will compute the daily wage of an employee. If the number of hours

worked exceeds eight hours add 30% to each excess hours as overtime rate.

Formula: Daily Wage = Rate per hour * No. of hours worked + OT pay

3. Write a JAVA program that will input a users choice based on the table below:

Choice Input the following Compute & Output

C for Circle Radius of a Circle Area = r2

S for Square Side of Square Area = s2

R for Rectangle Length & Width of a Rectangle Area = lw

T for Triangle Base & Height of a Triangle Area = 1/2 bh

4. Write a JAVA program that will compute for the net income of a particular employee. You have to

accept name, position, and number of days worked. The position has three categories: ifManager,

rate per day is P500; ifSupervisor, P400; ifEmployee, P300. Then after accepting the rate per day,

compute gross = rate per day * no. of days worked, compute for the bonus, if gross is >= 8000,bonus = 1000; if gross>= 5000, bonus = 750; if gross >= 3000, bonus = 500; if less, bonus = 0;

compute for the deductions: SSS is always 10% of gross; Medicare is always P100; and TAX, if

gross >= 7000, tax = 15% of gross; if gross >= 4000, tax = 10% of gross, if gross >=2000, tax = 5%

of gross. Then, compute forNet Income = gross + bonus total deduction. Then, display the net

income.

Sample Output:

Name: Richard

Manager Supervisor Employee

Position: s

Rate: 400

No. of Days Worked: 15 Gross: 6000 Bonus: 750 Deductions:

Tax: 600

SSS: 600

Medicare: 100Total Deduction: 1300

Net Income: 5450
