I'm pretty sure it's can be used in rural and remote areas, not 100 percent but seems right
We would use #include<iomainp> header file accordingly.
<h3>What is manipulator?</h3>
Helping functions known as manipulators can change the input/output stream. It simply affects the I/O stream using the insertion () and extraction (>>) operators, not the value of a variable.
Special functions known as manipulators can be used in an I/O statement to change a stream's format specifications.
Operators who format the data presentation are known as manipulators.The application should contain the file iomanip.h to access manipulators.The manipulators endl, ws, ends, and flush are those without arguments.
Setw (val), Setfill (c), Setprecision (val), Setbase (val), SetIOS Flags (flag), and ResetIOS Flags are examples of manipulators with arguments (m).
Two categories of manipulators are typically in use: Specified and Unspecified.

Answer:
The code for this class is shown in the explanation section
Explanation:
public class Circle {
private double radius;
private double diameter;
private double area;
public Circle(double radius, double diameter, double area) {
this.radius = 1;
this.diameter = diameter;
this.area = area;
}
public void setRadius(double radius) {
this.radius = radius;
diameter = radius*2;
area= Math.PI*(radius*radius);
}
public double getRadius() {
return radius;
}
}
