Create a program named FindSquareRoot that finds the square root of a user’s input value. The Math class contains a static method named Sqrt() that accepts a double and returns the parameter’s square root. If the user’s entry cannot be converted to a double, display an appropriate message, and set the square root value to 0. Otherwise, test the input number’s value. If it is negative, throw a new ApplicationException to which you pass the message “Number can’t be negative.” and again set sqrt to 0. If the input value is a double and not negative, pass it to the Math.Sqrt() method, and display the returned value
Create a class named Percentages whose main() method holds two double variables, and prompt the user for values. Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to: 2.0 is 40 percent of 5.0. Then call the method a second time, passing the values in reverse order.
An example of the program is shown below:
Enter a double >> 3.7 Enter another double >> 12.3 3.7 is 30.081300813008127 percent of 12.3 12.3 is 332.43243243243245 percent of 3.7
Task 01: Create the Percentages class.
Task 02: The computePercent() method displays the percent of the first argument of the second argument.
Task 03: The Percentages program accepts 2 double values from the console and displays the percent of first value of the second value and vice versa.
Write an application that computes and displays the day on which you become(or became) 10,000 days old. For example, if you we're born on January 1st, 2000, the output would be I will be 10000 days old on 2027-05-19. Grading Write your Java code in the area on the right.

- public setUpTrip(double, double): void Car's state is set to hold the speed of travel and distance to travel at that speed Precondition: none Postcondition: Car's state holds information on distance to travel and speed to travel Parameters: Average Speed to be driven, Distance to drive Develop and use an algorithm that calculates the amount of fuel used and the actual distance driven in the drive() method. The algorithm must use a formula that gives proportionately poorer mileage when the Car is driven faster or slower than its optimal speed. When a new Car object is instantiated, it is initialized with an optimal speed variable. Your fuel usage algorithm should set limits on how poor of MPG your car will get. You may add other methods and fields as needed. When a new Car object is created, the car’s odometer is set to a random number between 0.0 and 5.99, the car’s trip odometer is set to 0.0, its best fuel economy (MPG) is set to a random number between 15.0 and 54.99, its…arrow_forwardCreate a program named TipCalculation that includes two overloaded methods named DisplayTipInfo. One should accept a meal price and a tip as doubles (for example, 30.00 and 0.20, where 0.20 represents a 20 percent tip). The other should accept a meal price as a double and a tip amount as an integer (for example, 30.00 and 5, where 5 represents a $5 tip). Each method displays the meal price, the tip as a percentage of the meal price, the tip in dollars, and the total of the meal plus the tip. Include a Main() method that demonstrates each method. For example if the input meal price is 30.00 and the tip is 0.20, the output should be: Meal price: $30.00. Tip percent: 0.20 Tip in dollars: $6.00.
