Create a class IndependenceUSA and write code which asks the user to enter text that contains the American Independence day ( July 4th 1776). Read the date using the method next() 3 times. The user should enter the Independence day in the order month, day, year as shown in the first two runs below( we are not case sensitive) . Use the String method compareToIgnoreCase() to test the validi-ty of the date and print “Hurrah!” if the date entered is correct, or “No, no , no! Incorrect!” if the date incorrect is incorrect, or of the date entered in the wrong order. In other words, you compare your input to “July” , “4”, “1776” , in that order and you don't case for capital or small case letters.
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.
Make a class that represents an average of test scores. Make the class take an unlimited number of scores and calculate the number of tests taken along with the average.
Class name:
TestScores
Fields:
- name : String
- totalScore : double
- numScores : int
Methods:
+ TestScores(name : String)
+ addTestScore(earned : double) : void
+ getNumTestsTaken() : int
+ getAverage() : double
Write in java and use test case 1 as an reference

- This is java question: Create a class named Bottle, which contains the following attributes: isFull (boolean), drinkType (ex: water), fillLevel (max: 100). Then, create a method called drink, which takes an argument of how much liquid the user drinks. When the user calls drink, subtract the amount drank from the fillLevel and make sure that isFull is set to false. Lastly, create a constructor that initializes the object as a full bottle containing water.arrow_forwardcreate a class named checkup with fields that you read a patient number, blood pressure figures (systolic or diastolic), and two cholesterol figures (ldl and hdl). include a method named computeratio() that divides ldl cholesterol by hdl cholesterol and displays the result. include an additional method named explainratio() that explains that hdl is knowns as “good cholesterol” and that a ratio of 3.5 or lower is considered optimum pseudo codearrow_forwardProgram #5: a. Create a class named Circle with fields named radius, diameter, and area. Include a constructor that sets the radius to 1 and calculates the other two values. Also include methods named setRadius()and getRadius(). The setRadius() method not only sets the radius but also calculates the other two values. (The diameter of a circle is twice the radius, and the area of a circle is pi multiplied by the square of the radius. Use the Math class PI constant for this calculation.) Save the class as Circle.java. b. Create a class named TestCircle whose main() method declares several Circle objects. Using the setRadius() method, assign one Circle a small radius value, and assign another a larger radius value. Do not assign a value to the radius of the third circle; instead, retain the value assigned at construction. Display all the values for all the Circle objects. Save the application as TestCircle.java. I forgot to include "b" on my initial question submission. Secondly - is "b"…arrow_forward
