- !(7==7) true or falsearrow_forwardCalculator: Initially asks for two numbers. Afterwards, ask the user to select the operator and perform the calculation. Ask the user if a new calculation for two numbers is needed, or a computation for the previous number will be required. Test case 1: Ener two numbers : 15 25 Ener an operator (+, -, / ,-) :+ : 40 Output: Do you want to continue, exit or compute two numbers? (con, exit, com] exit Test case 2: Ener two numbers : 11.50 6 Ener an operator (+, -, /,-) :- Output: :5.50 Do you want to continue, exit or compute another two numbers? (con, exit, com] con Enter another number : 25 Ener an operator (+, -, 7,-) Output: Do you want to continue, exit or compute another two numbers? [con, exit, com] exit :137.50 Test case 3: Ener two numbers :23.50 14 Ener an operator [+, -, /,-1 :/ Output: Do you want to continue, exit or compute another two numbers? [con, exit, com] com :1.68 Ener two numbers : 14 Ener an operator (+, -, /,-) :+ Output: : Missing number Ener two numbers :14 15…arrow_forwardThis needs to be done in Java! (Calculating Sales) An online retailer sells five products whose retail prices are as follows: Product 1, $2.98; product 2, $4.50; product 3, $9.98; product 4, $4.49 and product 5, $6.87. Write an application that reads a series of pairs of numbers as follows: product number quantity sold Your program should use a switch statement to determine the retail price for each product. It should calculate and display the total retail value of all products sold. Use a sentinel-controlled loop to determine when the program should stop looping and display the final results.arrow_forward
- (Calculating the Product of Odd Integers) Write an application that calculates the product of the odd integers from 1 to 15.arrow_forwardDesign the worst calculator ever: an application that accepts two numbers from the user and, when a button is pushed, performs a single operation and displays the results. You may choose: Multiplication, Division, Subtraction, square root, or raising the first number to the exponent of the second number. Don't use addition as we already did that in class. The result must be displayed to the user only when an appropriately labeled button is pushed.arrow_forwardTOPICS: 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 9999arrow_forward
- 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...arrow_forward99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.arrow_forward6Assume you have three int variables: x = 2, y = 6, and z. Choose the value of z in the following expression: z = (y/x > 0) ? x :arrow_forward
- Fat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…arrow_forwardCreate an application that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you can use Button controls, or clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4. A winner is selected according to the following rules:• If one player chooses rock and the other player chooses scissors, then rock wins. (Rock smashes scissors.)• If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.)• If one player chooses…arrow_forwardFibonacci sequence: The first two numbers of the fibonacci sequence are 1 and 1, and sequential numbers are the sum of the previous two.
