Which ten buzzwords can be used to describe the Java programming language?
Simple Object oriented Distributed Multithreaded Dynamic Architecture neutral Portable High performance Robust Secure
Java is __________ so it can be programmed without extensive programmer training while being attuned to current software practices and programmers can be productive from the very beginning.
simple
Java is _________, so that current developers can easily learn the Java programming language
familiar
Java is _________, to take advantage of modern software development methodologies and to fit into distributed client-server applications
object oriented
Java is _________, for high performance in applications that need to perform multiple concurrent activities, such as multimedia;
multithreaded
Java is _________, for maximum portability and dynamic capabilities.
interpreted
Java is _________ because it provides extensive compile-time checking, followed by run-time checking.
The memory management model is extremely simple: objects are created with a new operator.
There are no explicit programmer-defined pointer data types, no pointer arithmetic, and automatic garbage collection.
Robust
Java is designed to operate in distributed environments, it has security features designed into the language and run-time system,
Java applications are _________ from intrusion.
secure
the Java Compiler TM product generates bytecodes–an _________ intermediate format designed to transport code efficiently to multiple hardware and software platforms.
architecture neutral
Java is ________ , so it solves both the binary distribution problem and the version problem. Also it is
strict in its definition of the basic language: it specifies the sizes of its basic data types and the behavior of its arithmetic operators.
Portable
The architecture-neutral and portable language platform of Java technology is known as __________
the Java virtual machine.
Java technology is both a ___________________ and a __________
Java technology is both a programming language and a platform.
The Java virtual machine is based primarily on which interface specification?
The POSIX specification–an industry-standard definition of a portable system interface.
Java has __________ by adopting a scheme by which the interpreter can run at full speed without needing to check the run-time environment.
high performance
The __________ runs as a low-priority background thread, ensuring a high probability that memory is available when required
automatic garbage collector
The _________ can execute __________ directly on any machine to which it and the _________ system have been ported.
Java interpreter
Java bytecodes
run-time
While the Java Compiler is strict in its compile-time static checking, the language and run-time system are _________ in their linking stages. Classes are linked only as needed. New code modules can be linked in on demand from a variety of sources, even from sources across a network.
dynamic
In Java, how do you obtain the effects of #define?
by using constants.
In Java how do you obtain the effects of typedef?
by declaring classes–after all, a class effectively declares a new type.
Why don’t you need header files in Java?
You don’t need header files because the Java compiler compiles class definitions into a binary form that retains all the type information through to link time.
In the Java programming language, all source code is first written in plain text files ending with the _________ extension.
.java
.java source files are compiled into _________ files by __________.
.class the javac compiler
A .class file does not contain code that is native to your processor; it instead contains _________ — the machine language of the Java Virtual Machine (Java VM).
bytecodes
The Java platform has two components:
The Java Virtual Machine
The Java Application Programming Interface (API)
