Body
The difference between an interface and a regular class is that you cannot specify implementation in an interface. To be more clear, you can only specify methods, but not implement them. If you want to have multiple inheritance then you have to <code>implement</code> multiple interface. Java does not support multiple inheritance due to the below reasons. Also to note that Interfaces are about subtyping and polymorphism, whereas, inheriting methods is about code reuse. From <a href="http://www.javaworld.com/javaqa/2002-07/02-qa-0719-multinheritance.html" rel="nofollow noreferrer">here</a>: <blockquote> The reasons for omitting multiple inheritance from the Java language mostly stem from the "simple, object oriented, and familiar" goal. As a simple language, Java's creators wanted a language that most developers could grasp without extensive training. To that end, they worked to make the language as similar to C++ as possible (familiar) without carrying over C++'s unnecessary complexity (simple). In the designers' opinion, multiple inheritance causes more problems and confusion than it solves. So they cut multiple inheritance from the language (just as they cut operator overloading). The designers' extensive C++ experience taught them that multiple inheritance just wasn't worth the headache. </blockquote> You can find this interesting <a href="http://javapapers.com/core-java/why-multiple-inheritance-is-not-supported-in-java/" rel="nofollow noreferrer">article</a> on the same:- <img src="https://i.stack.imgur.com/f3g8k.png" alt="enter image description here"> <img src="https://i.stack.imgur.com/3uBLd.jpg" alt="enter image description here">

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
