基于java的俄罗斯方块游戏开题报告和英文翻译内容摘要：

scarding is the Java unwise Java security check mechanism causes Java to have the toughness. 5th, the Java language is is usually used in the work environment, for this, Java provided a safety mechanism to guard against the malicious code the attack. Many security features has which besides the Java language, Java to has a safe guard mechanism through the work downloading kind (kind of ClassLoader), like the assignment different name space guards against the substitution locally of the same name kind of, the syllabified code inspection, and provides the safety control mechanism (kind of SecurityManager) to let Java apply the establishment security sentry. 6th, the Java language is the architecture Java procedure (suffix is the java document) is translated in the Java platform for the architecture neutrality byte code form (suffix is the class document), then may in realize in this Java platform any system to way suits in isomerism work environment and the software distribution. 7th, the Java language is may kind of probability originates from the architecture neutrality, moreover, Java strictly has also stipulated each master data type system itself also has the very strong probability, the Java piler is realizes with Java, the Java movement environment is realizes with ANSI C. 8th, the Java language is the mentioned above, the Java procedure is translated in the Java platform for the byte code form, then may in realize in this Java platform any system to movement, Java in the platform Java interpreter carries on the explanation execution to these bytes codes, the kind which in the implementation needs is written down in the joint stage in the movement environment. 9th, Java is a high with these explanation highlevel script language, Java indeed is a high fact, the Java running rate more and more approaches along with the JIT(JustInTime) piler technology development in C. 10th, the Java language is a the Java language, the thread is one kind of special object, it must or its sub(grandson) the kind founds by the Thread kind. Usually has two methods to found the thread: First, the operational construction was the Thread(Runnable) structure realizes one the Runnable connection object packing to bee a thread, its two, derived the subclass from the Thread kind and rewrites the run method, uses the object which this subclass founded is the thread. It is noteworthy that the Thread kind has already realized the Runnable connection, therefore, any thread had its run method, but in the run method has contained the code which the thread had to thread activity controls by group of methods. The Java language supports many threads at the same time execution, and provides between multithread the synchronized mechanism (key words is synchronized). 11th, the Java language is of Java language design goals is adapts in the dynamic change Java procedure needs the kind can dynamic write down the movement environment, also may write down the kind through the work which is also advantageous to the software , in the Java kind has a movement time expression, can carry on the movement time the type inspection. The Java language fine characteristic causes Java to apply has the inparable toughness and the reliability, this also reduced the application system maintenance API which 14 inlays to the object technology prehensive support and in the Java platform can reduce the application system the development time and reduces the Java translation one time, everywhere may move the characteristic enables it to be able to provide a everywhere available open structure and transmits the information between the multiplatforms the low cost way. In the Java technology, is worth paying attention also has JavaBeans, it is an open standard module architecture, it is independent in the platform, but uses the Java is one satisfies JavaBeans the standard the Java kind, usually has defined a real world thing or the concept. A JavaBean main characteristic including attribute, method and event. Usually has defined a real world thing or the JavaBean main characteristic including attribute, method and , supports the JavaBeans standard in one the development environment (for example Sun Java Studio and IBM VisualAge for Java), may visible operate JavaBean, also may use JavaBean which the JavaBean structure new goods e into the market. The JavaBean superiority also lies in the probability which Java , EJB (Enterprise JavaBeans) expands the JavaBean concept to the Java service end module architecture, this model support multilayer distributional object application. 三 Java tool bags introduced that： 1. AWT: It is Abstract Window ToolKit (abstract window tool bag) the abbreviation, this tool bag provided a set to carry on the interactive connection with the local graphical the AWT graph function and the operating system provide between the graph function has 11 corresponding relations, we are called it peers. In other words, when we use AWT es the ponent graphical user interface time, we in fact are the graph storehouse which provides in the use operating the different operating system graph storehouse provides the function is dissimilar, has the function in a platform in other platform then possibly does not exist. In order to realize a translation which the Java language declared, everywhere moves the concept, AWT can not but realize its platform independency through the sacrifice function, in other words, AWT provides the graph function is graph function occurring together which each kind of general operating system AWT is the dependence local method r。
