Answer 1

This moves nearly all the code out of main:

Please copy within 24 hours because that site will erase it at that point.
I didn't paste here because sololearn limits answers to 2048 characters and the code is longer than 2048.

The following requirement:
"Read in user input and verify that correct values were entered
Both, x,y > 0 and x<y" was in conflict with how you implemented the checks for cases when x is 0, y is 0, or x == y so I changed the operators to meet the requirements. You checked for x < 0 when the opposite of x > 0 is x <= 0.

Why do you limit to 3 errors? I don't see that requirement in your question.

Answer 2

Greig's code has two methods:
printPrimes(int lowerBound, int upperBound)
getValidRangeFromUser()

Answer 3

Response:

Why? I already did. Didn't you check the link https://ctxt.io/2/AACgkdD1Eg ?

main is very short because nearly everything was moved into separate methods. In other words, I wrote the other methods that the question is asking for.

Answer 4

A string cannot be split by the end of a line, such

System.out.print("\n Invalid input. Please enter numbers
greater than 0 or both.\n");
