TOPICS: Data and Expressions
MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM.
Write an application that prompts for and reads the numerator and denominator of a fraction as integers, then displays the decimal equivalent of the fraction.
Hint: This requires casting from integer to double before dividing.
Testing: Submit testing exhibits using the following inputs:0, 1 giving 0.0; 1, 2 giving 0.5; 3, 8 giving 0.375; 2, 3 giving 0.666...; 25, 7 giving 3.57128...
TOPICS: Data and Expressions
MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM.
Write an application that reads a value representing a number of seconds, then displays the equivalent amount of time as a combination of hours, minutes, and seconds. For example, 9999 seconds is equivalent to 2 hours, 46 minutes, and 39 seconds.
Hint: This requires using the % modulus operator. The trick with multiple units of measure like this is to start with the largest unit (hours) and work down.
Testing: Submit testing exhibits using the following inputs: 0, 1, 60, 3600, 3661, and 9999
Q2: Design a simply calculator using inputbox, one textbox and four buttons. The
integer values of the first and second number are entered by inputbox. Write the
codes to perform add, subtract, multiply, and divide where pressing on buttons.
Display the result operation in TextBox by using the following formula. 3*7=21

Salesperson's Commission Calculator (Nr 1, Page 408) Create an application that lets the user enter a salesperson's revenue sale and the rate of commission paid by the company, and display the commission earned. For example: • If a salesperson sells $100,000 in revenue while working with a company that pays 5 percent of the revenue, his/her commission check will be $5,000. • if a salesperson sells $100,000 in revenue while working with a company that pays 8 percent of the revenuo, his/her commission check will be $8,000. The program should have a method named CalculateDisplayCommission that receives the revenue sale by a salesperson and the commission percentage as arguments, and calculates and displays the commission earned by the salesman.

When an alarm fires, it will sound some noise. The user can turn it off, or choose to ‘snooze’. If the user does not respond at all, the alarm will turn off itself after 2 minutes. ‘Snoozing’ means to turn off the sound, but the alarm will fire again after some minutes of delay.

Also do the reverse. Calculate how many Dollars they will have when they return based on the number of Pounds they have when in England. Do the same for travelers going to Europe. Convert Dollars to Euro and Euro to Dollars. Program should allow you to enter the customer name, destination, money converted from and money converted to. After each customer transaction the name, destination, and both money amounts should be stored on a history file. Because the exchange rate changes daily you want a system that will easily adapt to the change. Your program needs to read text file (notepad) that will contain the conversion rates. That way each morning when you get to work you can put the new rates in the text file. Your program will read the text file as soon as you turn it on (Form_Load) and…arrow_forward
