Java

I am trying to find the path of resource using Paths like below and then copying some files at runtime. While at runtime it works perfectly fine. However while running locally for junit testing, it throws below error at the below first line while trying to get Path using URI. I am not using any zip/jar file so why I am getting the below stack trace. Am I missing something?

Path path= Paths.get(ABCD.class.resource("/").toURI());
String mockFileName="cacerts";
File mockFile= new File(path+File.seperator+mockfileName);

java.nio.file.FileSystemNotFoundException

Q1. Write a program using methods to find whether a point (x1,y1) lies on a circle of radius 2 cm and h = 5;  the equation of circle is given  by 〖(x-h)〗^2+〖(y-h)〗^2=r^2  . The method returns a Boolean value.

write a recursive function which takes 2 input parameters. The first is an employee id and the second is another employee id. We need this function to check if the second Employee is one of the direct or indirect managers, it must return true if the second employee is one of the reporting line for the first employee, otherwise it will return false

Employee
Emp Id int primary key,
Name varchar(50) not null,
Manager int references Employee (Emp_ld),
JobTitle int references JobTitle(JTId)
