This article mainly explains "what is the private modifier". Friends who are interested may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what is the private modifier"?
1. Private access modifiers are mainly used to hide implementation details and protect data.
2. Variables declared as private access types can only be accessed through the public getter in the class. Methods, variables, and constructors declared as private can only be accessed by their own class, and classes and interfaces cannot be declared as private.
Example
Public class Logger {private String format; / / Private methods cannot be accessed outside public String getFormat () {/ / define a method that throws the value of the format return this.format;} public void setFormat (String format) {/ / define a method that modifies the property this.format = format in the class through this method In the instance, the format variable in the Logger class is private, so other classes cannot directly get and set the value of the variable. To enable other classes to manipulate this variable, two public methods are defined: getFormat () (returning the value of format) and setFormat (String) (setting the value of format). So far, I believe you have a deeper understanding of "what is the private modifier". You might as well do it in practice.
