Lisp is a simple and powerful language with a very simple syntax:(+ 1 2)The above meaning is: + is a method or function, 1, 2 is a parameter, fn=1+2, that is, the sum is evaluated, the result is: 3Double brackets are used to remind the interpreter to start and end.Previously wrote an article in Iteye to briefly explain how to write Lisp's interpreter:http://gyc567.iteye.com/blog/2242960It also draws a sketch to illustrate:Because Lexer ( lexical analyzer ) is the main job is to convert the progr

Develop a compiler using java: code implementation Thompson constructor 1, input text preprocessing This program is the first step of building and implementing Thompson. Input text preprocessing. The code in this section can be extracted from the attachment of the cloud class. The directory structure of this Code is as follows: The purpose of our program is to convert the regular expression in the text fo

Using java to develop the compiler: Thompson structure, convert regular expressions to finite state automation Blog readers can go to my Netease cloud class to view the code debugging and execution process through video: In the previous section, we implemented a finite state automation through code and applied it to the identification of integer and floating point numbers. The whole process is the essence o

First, set the default encoding of JSP java files in eclipse Window-preference Example 1: In this case, all JSP Java will follow the default encoding. Troubleshooting: 1. If a JSP is garbled in eclipse, it must be because someone has changed the default code of JSP in eclipse, View the JSP property, as shown in Figure 2: If we see that the JSP code is GBK, if the JSP code is garbled, the default encodi

New Features of Java 8 and new features of Java 8 1. Interface Improvement A. Static methods can be defined in the interface B. More importantly, the method in the interface can be modified with default to add the method body. 2. Why cannot I use the default method to override the equals, hashcode, and toString methods

Interface Definition in Java 8 and Java 8 Interface Definition Define an interface. If there is a class to implement this interface, you must implement the methods defined in this interface; if the interface has been written, the class is also written, but if the interface is modified again, a method is added, before
