when i compile second class it give error " can not find symbol constructor Book(java.lang.String)

Answer 1

when i compile second class it give error " can not find symbol constructor Book(java.lang.String)It is just like the error says. Your code tries to create a new Book using a single String as the constructor argument, but you did not define a constructor in the Book class that uses a single String argument. The only constructor in Book takes 2 Strings and an int.
The following is exactly one String because there is exactly one pair of ". "Title: Absolute Java(Second Edition)\nAuthor: Walter Salvitch\nYear: 2006"For future reference, please use the code tags when posting code. Just highlight the code and click on the code button.
