(The Triangle class) Design a class named Triangle that extends GeomericObject. The class contains:
Three double data fields named side1, side2, and side with default values 1.0 to denote three sides of the triangle.
A no-arg constructor that creates a default triangle.
A constructor that creates a triangle with the specific side1, side2, and side3.
The accessor method for the three data fields.
A method named getArea() that returns the area of this triangle.
A method named getPerimeter() that returns the perimeter of this triangle.
A method named toString() that returns a string description for the triangle.
Note:- Please write a java code and also need an output for this program. (Also, let me know with what name file should be saved to get output)
Answer to each question should be a executable java code, tested and run
You implement each question in a separate .java file.
Note: Provide a copy of the code and screen shot for the output in the solutions. Explain the
working of the program in your own words.
2. Write a C# application that asks the user to input the required data to implement the three
methods below:
(Use Method Overloading to write the methods)
a. Method Area that takes as input, integer values I' (length) and 'w' (width),
calculates the area of a rectangle, and displays it. [Area = 1x w]
b. Method Area that takes as input, double values 'B' (base) and 'h' (height),
calculates the arca of a parallelogram, and displays it. [Arca = B x h]
c. Method Area that takes as input, a double value "B' (base) and an integer value
'h' (height), calculates the area of a triangle, and displays it. [Area = Bh]

- Do not use AI.arrow_forward"Type" doesn't specify a variable. Variables have data types. How can this idea explain any variable?arrow_forwardDo not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics: It contains at least eight characters. It contains at most 12 characters. It contains only alphabetic characters, digits and the underscore (‘_’) character. It does not start with a digit. It has a mix of upper-case and lower-case characters. Your class must contain the following method: public static String checkPassword(String input) This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.arrow_forward
- • FormulaEvaluator.java Requirements: Evaluate the following expression for any value of the variable x, and save the result in a variable of the type double. You must use the abs(), pow(), and sqrt() methods of the Math class to perform the calculation.

The latter may be easier to debug if you are not getting the correct result. 5x +3} ( √8x* — 6x²³ + 4x² + |20x+1) (9x³+7x² +5x+3) Next, determine the number of digits to the left and to the right of the decimal point in the result. [Hint: You can convert the double variable into a String variable using the static method Double.toString(result).
