Java is known to be a strongly type safe language,but there are some coding conventions and when these are used in some applications like persistent storage through serialization may generate unreliable or wrong output.Such cases should be caught and modified as per requirement to produce a ...
In this chapter we analyze and prove some structural properties of Java runs which are needed for the proof that Java is type safe (Theorem 8.4.1), and for the correctness proof of the compilation of Java to JVM bytecode (Chapter 14). This includes the reachability analysis for expressions ...
在编译期间,编译器无法检查这个 Object 的强制转型是否成功,如果仅仅依赖程序员去保障这项操作的正确性,许多 ClassCastException 的风险就会转嫁到程序运行期之中。 泛型技术在 C# 和 Java之中的使用方式看似相同,但实现上却有着根本性的分歧,C# 里面泛型无论是在程序源码中、编译后的 IL 中(Intermediate Language,...
Sometimes, a language is chosen because the developers of a company like it or know it, which may be reasonable. Sometimes a language is used because it is the latest and greatest, and this becomes a marketing tool to generate more public-relations interest in a product, which may not be ...
variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop....
The Java language [2] and virtual machine [3] provide many features to mitigate common programming mistakes. The language is type-safe, and the runtime provides automatic memory management and bounds-checking on arrays. Java programs and libraries check for illegal state at the earliest ...
The Java™ platform was designed with a strong emphasis on security. At its core, the Java language itself is type-safe and provides automatic garbage collection, enhancing the robustness of application code. A secure class loading and verification mechanism ensures that only legitimate Java code ...

A statically typed language is one in which variables have definite types, and where it is a compile-time error to assign a value of an incompatible type to a variable. Languages that only check type compatibility at runtime are called dynamically typed....
It is the view of this paper, however, that the language can stand on its own merits, and would be a success, even without the sometimes denigrated "Java hype". If we pause to consider the position of Java in 1996, we can see that in systems languages, the time was certainly ripe ...
