7. Java Generics (Generics) Overview Sample Code Detailed Explanation
Introduction: Java generics are a new feature introduced in JDK 5, which allows the use of type parameters when defining classes, interfaces and methods. General classes and methods can only use specific types. If you want to write code that can be applied to multiple types, this rigid restriction will be very restrictive to the code. Polymorphism is a generalization mechanism, but the constraints on the code are still too strong. There are many reasons for the emergence of generics, but one of the most compelling reasons is to create container classes. As a review article of generics, this article comprehensively explains the motivation, basic concepts, implementation mechanism, type erasure, use of wildcards, covariance and contravariance of generics.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
