pmd source code analyzer

It has been about 4 months since I studied PMD and customized the rules in my work. In fact, PMD has many worthy of my learning source code, but because of time did not have to pen. Today's brief summary of PMD and file filtering design of the

1. Lexical analyzer Function: Read the input characters of the source program and form them into a word base to generate and output a lexical unit sequence. Ii. Design Principles 1) symbol classification of c programming language: keywords, identifiers, constants, operators, operators 2) lexical analyzer Dual Output: 3) Regular Expression and state transition di

PMD is a source code parser. It finds common programming flaws, such as unused variables, empty catch blocks, unnecessary object creation, and so on. It supports Java, JavaScript, Salesforce.com Apex, Plsql, Apache Velocity, XML, XSL, and more.In addition, it includes CPD (copy-paste-detector, copy-paste detector).

To improve the quality of your code, in addition to improving logical control and understanding of business processes, there is room for improvement in the code itself, such as some potential problems that can be avoided early. Similar to the content of the coding code, if all rely on the coder to do their own checks, it will undoubtedly require a lot of work, if
