I have a Spring Scaffolded "find" method that correctly does not return a row from my database. If I print the contents of the pointer to the "find" method using "System.out.println("The contents of the Set are:"+ ptr);" what is printed is the following: "The contents of the Set are: [ ]" (with no space in between, I did that for clarity). When I compare using "if (ptr.equal("[ ]")..." it never goes inside the "if" statement. When I compare using "if (ptr.equal(null)..." it never goes inside the "if" statement. Or even "if (ptr.equal("")..." it never goes inside the "if" statement.

How do I make the check to test if row information was not returned from the Scaffolded "find" method? It seems that even when I use the exact characters printed in my debug statement, that doesn't work.

It sounds like the find method is returning an empty set. The way to check for empty set is this:

Code:

Set<YourEntity> result = findYourEntity();  // <<<<< Call the find method if (result == null || result.size()== 0) {  // <<<<< check for null or empty     // do no result logic here }

Thanks Cindy!
