Create three interfaces for the following using java language One method that accepts the number and return if its positive or negative, its square and its cube. Two methods that accepts 2 parameters and return their difference, product and quotient, the largest and smallest. Three methods that accepts 2 to 4 parameters and return their sum.

Don't give me AI generated answer or plagiarised answer. If I see these things I'll give you multiple downvotes and will report immediately.

Java program I need help creating a program that creates these two Christmas trees. It has a method that accepts two parameters (one for the number of segments and one for the height of each segment). The left tree has 3 segments with a height of 4 and the right one has two segments with a height of 5. If you could explain it, that would be great, I really want to understand how you do it.

QUICKLY please. Thank you. Please answer in python quickly  Below is code that defines a Quadrilateral class (a shape with four sides), which has four floating point instance variables that correspond to the four side lengths: import math class Quadrilateral:     def __init__(self,a,b,c,d):           self.a = a           self.b = b           self.c = c           self.d = d      def perimeter(self):            return self.a + self.b + self.c + self.d      def area(self):            print("Not enough information")      def __lt__(self, other):             return self.perimeter() < other.perimeter()   Define a Rectangle class that inherits from Quadrilateral, with the following methods: __init__(self, length, width): Override the __init__ method so that the Rectangle constructor only takes in two floating point numbers. Your constructor for Rectangle should only consist of a call to Quadrilateral’s constructor: don’t define any new instance variables. Override the area method to…

java-Find the area of circle using method... Write an application that prompts the user for the radius of a circle and uses a method called circleArea to find tarea of the circle. method method should return the computed area to the caller method.

Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this…
