Write a class encapsulating the concept of a circle, assuming a circle has the following attributes: a Point representing the center of the circle, and the radius of the circle, an integer. Include a constructor, the accessors and mutators, and methods toString and equals. I could get this far, I'm just a little confused on the adding the point constructor, accessor and mutator to my class.

Is it possible to combine the both in 1 Class? I tried it and every line in it had an error saying Circle had no return type. Any insight would be a returnable favor. Thanks again guys. You're talking about having constructors for multiple objects in a single class.

That can't be done. Java thinks that public point is a method that doesn't have a return type and so is syntactically incorrect.

You don't need to make a class for point. Java provides java. Point already. Just add a class level field for Point to your Circle class and you're good. Learn more. Creating a Circle Class in Java with Point center? Ask Question. Asked 8 years, 6 months ago. Active 5 years, 6 months ago.

Viewed 26k times. Would it look something like this? So where is the Point declaration in Circle class?? If I recall correctly a Point can be seen as a superclass of a circle with radius fixed to zero.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I'm trying to write a program that checks if a circle contains another circle, if a certain point is inside a circle, or the one I'm having trouble with, if a circle overlaps with another circle.

So my overlap method is all the way at the bottom but I don't really have anything inside because I'm not sure exactly what to do. I tried this :. So I'm not sure what else to try.

FYI, I'm trying to check if c1 overlaps with a circle with parameters 3, 5, 2. You can refer to Relative position of two circles. Learn more.

Tried this, still giving me an output of true, when it should be false. Awesome, tried multiple scenarios, this does work : ty! EDIT I tried this with a graph that does overlap and it gives me output of false.

Since: 1. Double The Double class defines an ellipse specified in double precision. Float The Float class defines an ellipse specified in float precision.

Type-specific implementation subclasses are available for instantiation and provide a number of formats for storing the information necessary to satisfy the various accessor methods below.

FloatEllipse2D. Parameters: x - the specified X coordinate to be tested y - the specified Y coordinate to be tested Returns: true if the specified coordinates are inside the Shape boundary; false otherwise. The rectangular area is considered to intersect the Shape if any point is contained in both the interior of the Shape and the specified rectangular area.

The Shape. This means that for some Shapes this method might return true even though the rectangular area does not intersect the Shape. The Area class performs more accurate computations of geometric intersection than most Shape objects and therefore can be used if a more precise answer is required. Parameters: x - the X coordinate of the upper-left corner of the specified rectangular area y - the Y coordinate of the upper-left corner of the specified rectangular area w - the width of the specified rectangular area h - the height of the specified rectangular area Returns: true if the interior of the Shape and the interior of the rectangular area intersect, or are both highly likely to intersect and intersection calculations would be too expensive to perform; false otherwise.

All coordinates that lie inside the rectangular area must lie within the Shape for the entire rectangular area to be considered contained within the Shape. This means that for some Shapes this method might return false even though the Shape contains the rectangular area. The Area class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required. Parameters: x - the X coordinate of the upper-left corner of the specified rectangular area y - the Y coordinate of the upper-left corner of the specified rectangular area w - the width of the specified rectangular area h - the height of the specified rectangular area Returns: true if the interior of the Shape entirely contains the specified rectangular area; false otherwise or, if the Shape contains the rectangular area and the intersects method returns true and the containment calculations would be too expensive to perform.

The iterator for this class is multi-threaded safe, which means that this Ellipse2D class guarantees that modifications to the geometry of this Ellipse2D object do not affect any iterations of that geometry that are already in process. Parameters: at - an optional AffineTransform to be applied to the coordinates as they are returned in the iteration, or null if untransformed coordinates are desired Returns: the PathIterator object that returns the geometry of the outline of this Ellipse2Done segment at a time.

ObjectSystem. The specified Object is equal to this Ellipse2D if it is an instance of Ellipse2D and if its location and size are the same as this Ellipse2D.

Returns: true if obj is an instance of Ellipse2D and has the same values; false otherwise. That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.

Float public abstract class Ellipse2D extends RectangularShape The Ellipse2D class describes an ellipse that is defined by a framing rectangle. The Float class defines an ellipse specified in float precision. Tests if the specified coordinates are inside the boundary of the Shapeas described by the definition of insideness. Tests if the interior of the Shape entirely contains the specified rectangular area.

Determines whether or not the specified Object is equal to this Ellipse2D. Returns an iteration object that defines the boundary of this Ellipse2D. Tests if the interior of the Shape intersects the interior of a specified rectangular area.

Ellipse2D This is an abstract class that cannot be instantiated directly.Object org. X3DConcreteElement org. X3DConcreteNode org. Hint: insert a Shape node before adding geometry or Appearance.

### Class Circle2D

Hint: descriptive DEF names improve clarity and help document a model. Hint: well-defined names can simplify design and debugging through improved author understanding. Warning: invoking the setUSE method on this node resets all other fields to their default values except for containerField and also releases all child nodes.

Warning: no other operations can be performed to modify a USE node other than setting an alternate containerField value. Warning: note that the setUSE method on this node resets all other fields to their default values except for containerField and also releases all child nodes. Warning: first start with findAncestorScene to check entire scene graph, or findAncestorX3D to check entire model document.

Warning: more than one element may be found that has the same name, this method does not handle that case. Warning: more than one element may be found that has the same DEF, this method does not handle that case.

A method contains double x, double y that returns true if the specified point x, y is inside this circle. See Figure A method contains Circle2D circle that returns true if the specified circle is inside this circle. A method overlaps Circle2D circle that returns true if the specified circle overlaps with this circle.

See the figure below. The circles would overlap if the radius of the first plus the radius of the second is more than the distance from the center point of the first to the center point of the second you can use the distance formula to calculate this. A circle would be inside the other circle if the above condition is true and distance between the centerpoints plus the radius of the smaller circle is less than the radius of the larger circle.
