What is "dynamic" about Java?

Question

hi
I'm new to Java and programing in general
There are few things I don't understand about Java and OOP in general.
1)
How does memory allocation in Java differ from memory allocation in, say, C or pascal?
* memory for all the variables declared in C is allocated at compile time. This way program can figure out at compile time whether there is enough memory to run a program.
In Java memory for primitive types is allocated at compile time, but memory for objects is allocated at run time.
So in other words, program has no way of knowing ( prior to running ) whether there is enough memory to run the program?
2)
Word "dynamic" is often used when talking about java. Does word dynamic in context of Java only refer to dynamic memory allocation, or does Java have some other "dynamic" features also?
thank you

No quiant like:
Sitting in the sun with a book on Java;
  going back inside by the lamp with Lava.
Swimming in the stream having nay a botha;
  laying on the shore to rest when I feel I'd ratha.
Flying paper kites at the beach in summer;
  feeling wind in my hair, hear a distant hum<m>er.
Going to the strip, hear the distant thunder;
  hear the flathead roar, see the red-light blunder.
