what is the difference between times(1) and atMostOnce() in Mockito verify method?
as both will result in same behavior so what is the difference between them?
is their any difference in their internal working?
verify(calculatorService, times(1)).add(10.0, 20.0);
verify(calculatorService, atMost(1)).add(10.0, 20.0);

It's the difference between == and <=:
times(1) must happen exactly one time.
atMost(1) can happen zero or one time.

From what I recall, it should be as follows:
times(1) -> will assert that your code called mocked method exactly once
atMost(1) -> asserts that your code hasn't called method more than one - note that even if you don't call method (0), the assertion should pass.

I'm getting this code smell in SonarQube "the return value of "format" must be used".
Sample code:
ShiftStartDate.format(DateTimeFormatter.ofPattern("MMddyyy")
ShiftEndDate.format(DateTimeFormatter.ofPattern("MMddyyyy")):
I tried, but I'm not sure what to return.
format is not mutating the Date, but rater returns a new String with the provided pattern. Sonarqube is telling you, that you do nothing with the return value. So either assign it to a variable, which you will use or remove the invocations altogether.

Is there a more elegant way to achieve by using java 8 or above the eighth version what's below?
List<String> exampleList = List.of("test","test1");
exampleList.stream().filter(s -> s.equals("test")).findFirst();
Thanks in advance
It depends on what exactly you want to do.
If you just want to check if "test" is in one of the elements, you could just use .contains():
List.of("test","test1").contains("test");
If you want to find the first element fitting a condition, you can omit creating the list and directly create a Stream:
Stream.of("test","test1").filter(s->"test".equals(s)).findFirst()
If you want to check if an element fitting the condition exist, you can use anyMatch:
Stream.of("test","test1").anyMatch(s->"test".equals(s))
This is probably the best your going to get.
List<String> exampleList = List.of("test","test1");
exampleList.stream().filter("test"::equals).findFirst();
If its reused you can just make a method out of the 2nd line. Question has also already been answered here

This is the main method from where I am trying to pass values to the skill class which accepts array. I do not want to give employee e1 all the skills but just s4, how can I do that so my code becomes logical and correct
You have different way to achieve this.
Taking into consideration the piece of code you showed above, the easiest way to do that which doesn't imply to add any additional method to the Employee class, is to create a new array of Skill while invoking setEmployeesSkills on e1, so your code will appear more or less like this:
e1.setEmployeesSkills(new Skill[]{s4});
Hope that is what you are looking for, otherwise please share more info and I will try to help you further.

I have read on many blogs and website that method overloading make code more readable:
Method overloading increases the readability of the program.(Source)
where as official documentation say:
Overloaded methods should be used sparingly, as they can make code
much less readable.
In that case you have to do some observation to come to the conclusions
Which is better?
Case 1
System.out.print(“Hello”);
System.out.print(12);
OR
Case 2
System.out.printString(“Hello”);
System.out.printInt(12);
As seen Case 1 is more readable and can be remember easily in comparison to Case 2 . This above Case 1 print method is overloaded as seen in source . So thats why java creator dint implement Case 2.
Hence ill go with overloading is more readable and also if its not readable then java developers would have implemented Case 2.

it is possible to assign that big number in java? i need to make a calculation of 39 digits value. could any help? Thanks
Problem:
Consider the following composite number:
340282367237851113557325445936183246849
Write a Java method to find two numbers whose product is the above number.
I guess you need to check out the BigInteger of the java API. That might be able to store your results of those much big numbers. Read the documentation,
http://docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html
