Math 130 Java programming Dear Bartleby, I am a student beginning in computer science. May I have some assistance on this lab assignment please? Thank you.
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…

Q1. Write two Java classes for calculating the power m" using the recursive method as follow: Class A A. Define two private variables in the class: names n and m. B. Define a constructor takes two parameters m and n and assign them to the class variables. C. Define setter and getter methods. D. Define a recursive method which take two parameters n, m and calculates the power using recursion. Class B: A. Define the main method. B. Define an object of class A and call its constructor which takes two parameters C. Call all the defined methods in Class A. Send the values 4,5 when call the recursion method.

1. Instructions: The program you will analyze is shown below. The program listing contains a class definition followed by a main program. Your task is to find and write the missing code lines to make the program work correctly. Use the output statements from the print() statements to reveal this mystery :-) Please write the missing code lines clearly in the empty boxes. ###### start of Rectangle class class Rectangle: def init (self, length, width): self.length length self.width = width def GetLength (self): return self.length def GetWidth(self): return self.width def GetArea (self): return self.length * self.width def SetScale(self, scale): self.length self.length * scale self.width self.width * scale #### start of main program rec Rectangle (3,5) %3D print ('Rectangle Area: ', rectangleArea) for ES in range (2,5) : width = rec.GetWidth()
