Hi Friend,

Try the following code:

import java.util.*;
public class CheckPoint{
    public static void main(String[]args){
        Scanner input=new Scanner(System.in);
        System.out.print("Enter the radius of the circle : ");
            double r = input.nextDouble();
            System.out.println();
            System.out.print("Enter x coordinate of the centre of circle : ");
            double x1 = input.nextDouble();
            System.out.print("Enter y coordinate of the centre of circle : ");
            double y1 = input.nextDouble();
            System.out.println();
            System.out.print("Enter x coordinate of the point: ");
            double x2 = input.nextDouble(); 
            System.out.print("Enter y coordinate of the point: ");
            double y2 = input.nextDouble();
            double b=2;
            double x=Math.pow(x2-x1,b);
            double y=Math.pow(y2-y1,b);
             System.out.println();
            double check =Math.sqrt(x+y);
            if (check < r){
                System.out.println("Point lies inside the Circle");
            }
            else if (check == r){
                System.out.println("Point lies on the Circle");
            }
            else{
                System.out.println("Point lies outside the Circle");
            }
}
}

Thanks
