I just started reading a Java book and wondered; which access specifier is the default one, if none is specified?

The default visibility is known as "package-private" (though you can't use this explicitly), which means the field will be accessible from inside the same package to which the class belongs.

As mdma pointed out, it isn't true for interface members though, for which the default is "public".

See Java's Access Specifiers

What is the default access specifier in Java?, Java Access Modifiers - Public, Private, Protected & Default: Access Modifiers is the way of specifying the accessibility of a class and its members.. There are four access specifiers in Java: public, private, protected, and default. Three of them use their associated word, while default uses none. They appear as follows: [code]public class JavaApplication { Object object1; public Object

The default specifier depends upon context.

For classes, and interface declarations, the default is package private. This falls between protected and private, allowing only classes in the same package access. (protected is like this, but also allowing access to subclasses outside of the package.)

class MyClass   // package private
{
   int field;    // package private field

   void calc() {  // package private method

   }
}

For interface members (fields and methods), the default access is public. But note that the interface declaration itself defaults to package private.

interface MyInterface  // package private
{
   int field1;         // static final public

   void method1();     // public abstract
}

If we then have the declaration

public interface MyInterface2 extends MyInterface
{

}

Classes using MyInterface2 can then see field1 and method1 from the super interface, because they are public, even though they cannot see the declaration of MyInterface itself.

Java Access Modifiers, What are the differences between protected and default access specifiers in Java​? JavaObject Oriented ProgrammingProgramming. The  The access modifiers in Java specifies the accessibility or scope of a field, method, constructor, or class. We can change the access level of fields, constructors, methods, and class by applying the access modifier on it. There are four types of Java access modifiers: Private: The access level of a private modifier is only within the class. It cannot be accessed from outside the class.

If no access specifier is given, it's package-level access (there is no explicit specifier for this) for classes and class members. Interface methods are implicitly public.

What are the differences between protected and default access , Java provides a default specifier which is used when no access modifier is present. Any class, field, method or constructor that has no declared access modifier  The default access specifier for a class is private. The default access specifier for a struct is public. It does not matter if it is a function or a variable.

The default visibility (no keyword) is package which means that it will be available to every class that is located in the same package.

Interesting side note is that protected doesn't limit visibility to the subclasses but also to the other classes in the same package

Introduction to Java Access Modifiers, We do not explicitly define the default access modifier in JAVA . A variable or method declared without any access control modifier is available to all other  Access specifiers for classes or interfaces in Java. In Java, methods and data members of a class/interface can have one of the following four access specifiers. The access specifiers are listed according to their restrictiveness order. 1) private 2) default (when no access specifier is specified) 3) protected 4) public But,

Which is the default access specifier in Java?, Access modifiers in java or java access modifiers such as private, default, protected and public with examples applied on data member, method, constructor or  default(no specifier): When you don't set access specifier for the element, it will follow the default accessibility level. There is no default specifier keyword. Classes, variables, and methods can be default accessed.Using default specifier we can access class, method, or field which belongs to same package,but not from outside this package.

Access modifiers in java, private; default (package); protected; public. Each of these Java access modifiers will be covered in the  The Default access modifier is package-private (i.e DEFAULT) and it is visible only from the same package. Default access modifier - If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes).

Java Access Modifiers, Four access modifiers in java include public, private, protected and default. Private and Protected keywords cannot be used for classes and  Java Access Modifiers - Public, Private, Protected & Default: Access Modifiers is the way of specifying the accessibility of a class and its members..

Different Types Of Access Modifiers In Java, When we don't use any keyword explicitly, Java will set a default access to a given class, method or property. The default access modifier is  As the name suggests access modifiers in Java helps to restrict the scope of a class, constructor , variable , method or data member. There are four types of access modifiers available in java: Default: When no access modifier is specified for a class , method or data member – It is said to be having the default access modifier by default.

Comments
  • The correct term is 'access modifier'. The word 'specifier' does not appear in the JLS.
  • incorrect - not true for interface members. the default access is then public
  • It is known as 'package private' actually. Third-party web sites are not normative references. You should be citing the JLS only.
  • "Package private" (sometimes written in source as /* pp */) is only a convenient name for default access. It's not the JLS name.
  • @Tom - that's correct, the JLS uses "default access". I could have written "the default is default access". But that didn't seem too helpful!
  • First sentence is spot-on, but the fact that an outer class can't be private doesn't prove there is no such thing as an access specifier in Java.
  • @EJP This is just an example. What i am saying is that the term access specifier is used in other languages like c, dot net etc but technical term in java for this is modifiers. If you use eclipse or any other IDE you can see that at the time of creating new class we are asked to provide modifiers name and in list they provide public, private, abstract, etc
  • In my example what i try to say that compiler give error message : modifiers private is not allowed, it is not giving message like access specifier private not allowed. So the technical term we should say is modifiers in java not access specifier in java
