Question

Hello there. I'm making a class called LibraryRecord, which has 2 constractors. The first one "manages" 6 attributes of an object and they are the following: 1. The title of the book 2. The writer/author 3. The "ISBN"- a serial number. 4. The publisher 5. The year it was published 6. If it's still being published or not. The 1st constructor "accepts" all 6 variables and creates an object Library Record with them. The 2nd constructor only contains the first 5 elements stating the book is still being released. In the program I should include get-methods for every element(all 6 elements), also I should include a set-method with a flag that shows if it's being released or not. And I should do an appropriate use of the method toString. Lastly,I need to make a simple program to test it out.
I get 2 errors when i try to compile the Main Program.

TestLibraryRecord.java

public class TestLibraryRecord {
    public static void main(String[] args) {
        LibraryRecord r = new LibraryRecord("One story", "NoName", "AADS1234533", "3456233245", "NoName", "2015");
        System.out.println(r.toString());
        System.out.println("=========================================");
        LibraryRecord r1 = new LibraryRecord("One story", "NoName", "AADS1234533", "3456233245", "NoName", "2015", true);
        System.out.println(r1.toString());
    }
}
