The below table summarise above access modifiers with respect to different classes in the same package or other packages and subclasses. 下表总结了关于同一包或其他包和子类中的不同类的上述访问修饰符。 Let’s write some simple classes where we will see the java access modifiers in action. 让我们...
The table below summarizes the available access modifiers. We can see that a class, regardless of the access modifiers used, always has access to its members: 7. Canonical Order of Modifiers The order of modifiers isn’t strictly enforced in Java. However, the Java Language Specification (JLS)...
The protected access modifier cannot be applied to class and interfaces. Methods, fields can be declared protected, however methods and fields in a interface cannot be declared protected. Protected access gives the subclass a chance to use the helper method or variable, while preventing a nonrelate...

What are Access Modifiers? In Java, access modifiers are used to set the accessibility (visibility) of classes, interfaces, variables, methods, constructors, data members, and the setter methods. For example, class Animal { public void method1() {...} private void method2() {...} } In...
Public is the most well known of the Java keywords. Public is also the easiest of the Java access modifiers because of its nature. A variable or method that is public means that any class can access it. This is useful for when the variable should be accessible by your entire application....

1. Access Modifiers Let’s quickly compare these access modifiers in nutshell. public– accessible everywhere protected– accessible in the same package and subclasses outside the package default– accessible only in the same package private– accessible only in the same class ...
1.访问修饰符(access modifiers),如public/private等 成员的访问控制符 public public即公共的,在Java中public是限制最宽的修饰符,其可修饰类、字段、方法;且可跨类访问,而且可跨包访问 default(默认) 若未添加任何修饰符,即为默认访问权限,即包内可访问。用默认修饰符修饰的类、字段、方法,都只能在同一个包内...
