One of the questions I saw today when I looked at the community quiz was about the implementation of Compartor in the Ali Development Manual, which is recommended to achieve symmetry, transitivity, and reflexivity. The answer mentions the problems that arise in the JDK7 if such a property is not satisfied.
This is when I know the original JDK7 and above version, th

Design by contract is a design technique summarized by Bertrand Meyer, and is also the main feature of the Eifel language invented by Meyer. However, the scope of this principle is not limited to Eifel, but all programming languages.
The core of design by contract is assertion ). The so-called "assertion" refers to a Boolean statement that is a

Introduction: When Developing enterprise software, Java code often needs to interact with external components. Regardless of whether an application must communicate with a legacy application, an external system, or a third-party library, using an uncontrollable component introduces the risk of unintended results. IBM's IT expert Filippo Diotalevi shows how aspect-oriented programming (AOP) reduces this risk by helping you design and define explicit contracts between components while keeping your
A U.S. congressman in Florida recently proposed a bill that would create a legal basis for block-chain data and smart contracts if passed. The House Act 1357 introduces a number of provisions that, without violating any existing laws and regulations, block-chain ledger and intelligent contracts should be considered legally binding data storage methods.
It is noteworthy that the Act states that "records or contracts obtained through block chain technology are electronic, electronic records" and
