TASK DEFINITION: You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
PROBLEM: Zippers were first used in men's trousers in 1937.

SOLUTION: Who were the first users of the zipper?

PROBLEM: Oftentimes, we mean "An organized, militant Evangelical movement originating in the United States in the late 19th and early 20th century in opposition to Protestant Liberalism and secularism, insisting on the inerrancy of Scripture."

But the concept of fundamentalism can be extended to any ideology or theology whose tenents include a strict adherance to a code, especially one which demands the observance by persons who do not subscribe to that code.

Naturally, this makes for a source of conflict. And an understandable one at that. For example, say you believe some act is wrong. Furthermore, you believe you have a duty to prevent wrongdoing altogether. Consequently, you have a moral obligation to prevent any person from doing that act - including people who do not think that act is wrong.

Any critical examination of a dogmatic theology or ideology will reveal how necessary this is, yet any objective look at disparate cultures will reveal how subjective - and frightening - this can be.

The hope of the future is that fundamentalist evangelism will be enacted by appeal to reason rather than dictates of law. Ideally, people would choose to perform 'right' acts for their own sake, rather than out of fear of punishment.

SOLUTION: what does fundamentalism mean?

PROBLEM: Hi,
As such I have never really been to Java. But the thing that you have asked is fairly technology independent. I will try to explain them in as much non-tech terms as possible.

Serialization:
Serialization is a process of saving state of an object in some format. State of an object means its current value which in turn comprises of the values of the members of the object. For example, if I have a class Student, having RollNo and Name as its members(properties), and an object of Student class 'Deobrat' is created with ROllNo=01 and Name="Deobrat Singh". Then serialization of the object Deobrat would mean, saving this object somewhere (either in memorystream or in a filestream or on a networkstream) in such a way that it can later be reconstructed to again form the same object.
To be a bit more elaborate, consider an example where I have to send an object across a network to some remote computer (something that we do in WebServices). Now, in this case, the object itself cannot be sent because the network doesn't recognise what an object is. It simply understands a stream of bytes and nothing else. Serialization allows us to convert this object into a stream of bytes which then could be sent across the network to the remote computer.

Deserialization:
Deserialization is exactly the reverse process of Serialization. It means, to convert the stream of bytes in order to reconstruct the original object (or object state to be more precise). In the Web Service example scenario taken above, the Service Request broker will simply extract the stream of bytes, Deserialize them to create the object and give it to the class that is supposed to process it.

Externalization:
Serialization is achieved in 2 ways.
Using the Serializable interface which tells the runtime(or JVM) that the class has only premitive types that are serializable by themselves so the runtime can go ahead and use it's own code to serialize any object of this class.
On the other hand, if you want to write a class that has complete control over the process of serialization & deserialization, you implement Externalizable interface. In this case, when an object of your class has to be serialized, the runtime will not do it by itself. Rather it will call a method writeExternal to serialize the object. You will have complete control over the stream and format of the data to serialize. While deserializing the object, again the runtime will call readExternal method on your class which is supposed to read the stream and reconstruct the object state.
A word of caution:

In most cases, it is sufficient to use the Serializable interface because you wont have to write code for the serialization process. But in certain cases where you have a very heavy class with a lot of properties which need not be sent to the other end, it is better to write your code using Externalizable interface, because, then you will have complete control over which properties need to be serialized and which need not be serialized. While deserializing, again, your class will know which are the properties that must have been serialized and accordingly, you can recreate the object state.

In general, if you want a custom (in most cases, partial) serialization/deserialization to happen, you use Externalization.
