Hi There,
There's some very useful explanation about implementing Unions in java..

Hope that helps you too..

Objects that do not implement Serializable.
In C and C++ Variant Records correspond to Unions. There is no corresponding capability in Java
You can find out how to implement threads using Java through Stacker Overflow, Java Script Source, Java Code Geeks, Free Programming Resources and other websites. There are also tutorials on college sites as well as Youtube.
No. Java programs run in the Java Virtual Machine (JVM) - without it your computer won't know how to handle Java bytecode.
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
To create an abstraction or a blueprint for a class to implement later.

Zero. By default they do not implement any interfaces.
Java does not support multiple inheritance; a subclass cannot have more than one parent. Java compensates for this with interfaces. A class can implement multiple interfaces, but can only extend one class.
The main advantage is that you don't have to implement those collections yourself. Java provides very efficient implementations for dozens of collections.

In java we can implement more than one interfaces for a single class but we can't extend a class to more than one super class so ,java indirectly supports multiple inheritance.
