`There’s a employee list, first 4 characters shows employee joining year. I want to get all employees who joined in 2023. I’m using java , stream and filter method to do this.

Let’s say I have a code that filters some elements from one list and then adds the elements to the second list and then removes the elements from the third list. I can do it using a lambda and 2 instructions, but wouldn’t it be easier and more readable to have a variable length parameter list in the terminal operations?

I have learnt about Stream API. Do you have any practice for me? This is also implement lambda expression and what I have to study?(I learn by myself)
