Homework 4

This program is useful for calculating the intersection of a circle with other shapes or determining whether a point is within a certain range. This Java program reads in a radius and a point (x, y) from the user and determines if the point is inside a circle with center at (0,0) and radius = R. The program first reads in the radius and the point coordinates from the user using a Scanner object. It then uses the Pythagorean theorem to calculate the distance between the point and the center of the circle. If the distance is less than the radius, the point is inside the circle. On the other hand, if the distance is greater than the radius, the point is outside the circle. The program then prints out the appropriate message to the user informing them of the result.
• Create a new project named Homework4

• Create a new class named PointInCircle

  Open the class PointInCircle in BlueJ and delete all the text

• Copy and paste this main( ) method into the PointInCircle class:

  import java.util.Scanner; public class PointInCircle { public static void main(String[] args) { // Write your program below this line } }

  Write the program inside the main( ) method.
