Every circle has a center and radius. Given the radius, we can determine the circle’s area and circumference. Given the center, we can determine its position in the x-y plane. The center of a circle is a point in the x-y plane. Please do the following: Design the class Circle that can store the radius and the center of the circle based on the class Point we talked in the class. You should be able to perform the usual operation on a circle, such as setting radius, printing the radius, calculating and printing the area and circumference, and carrying out the usual operations on the center. Write a test program to test your program. Note: Java Programming, Please at the end also put all final code in one program so I can test it in dr.java. And Do use Point code given below.

Question
Every circle has a center and radius. Given the radius, we can determine the circle’s area and circumference. Given the center, we can determine its position in the x-y plane. The center of a circle is a point in the x-y plane. Please do the following:
- Design the class Circle that can store the radius and the center of the circle based on the class Point we talked in the class. You should be able to perform the usual operation on a circle, such as setting radius, printing the radius, calculating and printing the area and circumference, and carrying out the usual operations on the center.
- Write a test program to test your program.
Note: Java Programming, Please at the end also put all final code in one program so I can test it in dr.java. And Do use Point code given below.
Point code:
// class Point
public class Point
{
protecteddoublex, y; // coordinates of the Point
//Default constructor
publicPoint()
{
setPoint( 0, 0 );
}
//Constructor with parameters
publicPoint(doublexValue, doubleyValue )
{
setPoint(xValue, yValue );
}
// set x and y coordinates of Point
publicvoidsetPoint(doublexValue, doubleyValue )
{
x = xValue;
y = yValue;
}
// get x coordinate
publicdoublegetX()
{
return x;
}
// get y coordinate
publicdoublegetY()
{
return y;
}
// convert point into String representation
publicStringtoString()
{
return"[" + String.format("%.2f", x)
+ ", " + String.format("%.2f", y) + "]";
}
//Method to compare two points
publicbooleanequals(PointotherPoint)
{
return(x == otherPoint.x &&
y == otherPoint.y);
}
//Method to compare two points
publicvoidmakeCopy(PointotherPoint)
{
x = otherPoint.x;
y = otherPoint.y;
}
publicPointgetCopy()
{
Pointtemp = newPoint();
temp.x = x;
temp.y = y;
return temp;
}
// print method
publicvoidprintPoint()
{
System.out.print("[" + String.format("%.2f", x)
+ ", " + String.format("%.2f", y) + "]");
}
} // end class Point
