JAVA PROGRAMMING

Write two java files for this assignment: Circle.java, and Main.java.

The Circle.java file will create an actual class.  

The Circle class:

MEMBER VARIABLE

  • double radius
  • double x
  • double y

Eight methods:

  • Six of the methods are simple:  getter’s and setter’s for x, y, and radius.
  • There should also be a getArea method that returns the area (derived from the radius)
  • A doesOverlap method.  This method should accept a Circle as an argument, and return true if this circle overlaps the circle that the method was invoked on.  [Note: two circles overlap if the sum of their radius' is greater than or equal to the distance between their centers.]

 

void setX(double value)

double getX()

void setY(double value)

double getY()

void setRadius(double value)

double getRadius()

double getArea()

boolean doesOverlap(Circle otherCircle)

 

second class will be the typical replit Main class, with its static main method .It should contain code that tests the Circle class. submit code that meets the criteria below after testing

  • Allocate and initialize at least three Circle objects. Two of the three should overlap, and two should not.
  • Display the areas of the three circles
  • Invoke doesOverlap on Circles to show which circles overlap.
