New API features JDK 6 provides an API for calling the compiler at runtime. We will assume that this API is applied to JSP technology later. In traditional JSP technology, the following six steps are usually required for servers to process JSP: Analyze JSP code; Generate Java code; Write Java code into memory; Start another process and run the compiler to compile Java code; Write class files into the

Computers do not understand high-level languages, and of course they cannot execute high-level languages directly. Computers can only understand machine language directly, so any language must be translated into machine language. Programs written in any programming language are ultimately executed by the machine code (01 sequence) of the underlying machine, whether it is a compiled or interpreted language. The source code for any high-level programming language program is a sequence of character

Problem: Define an empty type, which does not have any member variables or member functions, and does a sizeof operation on this type, the result is?The result is 1, because an instance of an empty type does not contain any information, and the result is 0 after the reason that sizeof evaluates, but when declaring any type of instance, the memory must occupy a certain amount of space, otherwise the instances cannot be used, and the compiler determines

In the first part of this series, I want to summarize the compiler constructs and help you understand the purpose of each component in the compiler. Presumably we look at other compiling principles of the book, mostly in the first chapter or preface and other places, the compiler into a number of modules, and then each module is responsible for the specific phase

There is already a problem with completing the operating system A senior computer student how to complete a simple operating system within six months (probably only at night). What should we learn? In the answer to see a lot of people recommend to write compiler, want to know for example to write JavaScript or Python compiler, what needs to do, how to arrange?

There is already a problem about how a senior computer student can complete a simple operating system within six months (around the evening. What should I learn? In the answer, I see many people who recommend writing compilers. I want to know what the compiler needs to do for example, to write JavaScript or Python. How can I arrange it? The operating system has been completed. How can a senior computer student complete a simple operating system in six

1. Compiler 1.1. Compile period classificationA *.java file is generally compiled and run, and involves two types of compilation periods:① Compile-time compilation: The process that generally represents *.java->*.class (contains bytecode)-also called front-end compilation.② Run-time compilation: generally represents the process of *.class-> machine code-also called back-end compilation.1.2. Compiler classif

Compiler stack protection technology in GCC Buffer overflow, represented by stack overflow, has become the most common security vulnerability. Security problems are common. As early as 1988, Morris, a graduate student in the Computer Science Department at Cornell University, used a Unix fingered program overflow vulnerability to write a malicious program and spread it to other machines, as a result, 6000 servers on the Internet were paralyzed, account

Why is the size of an empty class not 0?This is necessary to ensure that two different objects have different addresses.The instantiation of a class is the allocation of an address in memory, with each instance having a unique two address in memory.Similarly, an empty class is instantiated, so the compiler adds a byte implicitly to the empty class so that the empty class is instantiated with a unique address.Therefore, the empty class of sizeof is 1,
