difficult exercise in racket sheme programming??????????
A function named occurrences that takes as parameters two arguments, a and b. If a is not a list
then the function should return #f. Otherwise it should return the number of times b is found in

You are a manager of a parking lot and decide to keep track all the cars parked in your lot. You want to know the maker, model, color, and license plate of the cars. Since you learned about ArrayList and you like to use an ArrayList to keep track of cars entered the lot. Each time a car left the lot, the remove method of ArrayList class can be used. Each time a car entered, add method can be used. To keep track how many cars in the lot, the size method can be used.
But before you write your application to create a class called MyParkingLot, you have to write a class call Car which contains all the information you need as describe in the previous paragraph. Also develop constructor(s) and getters or setters as needed so that you can retrieve (get) and record (set) information such as maker, model, color, and license plate number.
For MyParkingLot class, it shall consist of an ArrayList which will be used to maintain the information of all the cars in and out of this parking lot.

I have to write a test class for a program and a counter class, its a course work in my university. I'm in my first year, so it may not be as complex for you guys as it is for me. I wanna know like how much it'll cost to do this?, like an approximate value

// Qs. Write java program that contains the following 2 classes.
(i) Circle class that contains a radius field and getArea method that calculates its area.Give it a constructor where u pass in the radius.
(ii) TestCircle class which creates an array of 100 circles, each with a a random radius and prints out the sum of the areas , the biggest & smallest areas



class Circle {

private float radius;
public Circle(float r)
{
this.radius=r;
}
public float getArea()
{
return (float)(Math.PI*radius*radius);
}
}

class circle7
{
public static void main(String[] args)
{
Circle circles[]= new Circle[100];
for(int i=0; i<circles.length; i++)
{
circles[i]= new Circle((float)(50*Math.random()));
showAreas(circles);
System.out.println("the sum is"+ areaSum(circles));
System.out.println("the minimum is"+ minArea(circles));
System.out.println("the maximum is"+ maxArea(circles));

}
public static float areaSum(Circle c[])
{
float sum= 0;
for(int i=0; i<c.length; i++)
{
sum+= c[i].getArea();
}
return sum;


}

public static float minArea(Circle c[])
{
float min= c[0].getArea();
for(int i=1; i<c.length; i++)
{
if(c[i].getgetArea()<min)
min= c[i].getArea();
}
return min;

}




public static float maxArea(Circle c[])
{
float max= c[0].getArea();
for(int i=1; i<c.length; i++)
{
if(c[i].getgetArea()>max)
max= c[i].getArea();
}
return max;

}
public static void showAreas(Circle c[])
{
for(int i=0; i<c.length; i++)
{
System.out.println(c[i].getArea());
}


}

}


// Can someone plz find the errors in the program? Cuz the compiler is giving 8 errors.
