efine a Java class called Circle with data fields for centre coordinate values , circle radius and circle area, where the area is given by Math.PI*radius*radius. The class also has a Circle constructor with arguments for the centre coordinate ( x,y) and radius. The class also has a public method for getting circle area. [8 marks
class Circle{
double x;
double y;
double radius;
double area ;
Circle(double a,double b,double c){
x = a;
y = b;
radius = c;
}

public double getArea(double d){
return Math.PI*radius*radius;
}
}

You never use the global area variable. And why does your getArea() function take a parameter that you never use?
