Are the private access specifiers in Java and C plus plus the same?

No.
In Java, the private access modifier restricts member access to the class in which the member is declared. But in C++, private members are also accessible to friends of the class in which they are declared. The rough equivalent in Java would be package private access.
Not that Java doesn't have access specifiers, it has access modifiers. When no modifier is specified, default access is implied, which is package private for classes and public for interfaces.

∙ 10y agoJava has the same access specifiers as C++ which work in the same way. The only difference is the way in which default access works. In C++, default access is private for class structures and public for struct structures. In Java, default access lies between protected and private, allowing access from the class itself as well as from other classes within the same package, however subclasses have no access unless contained in the same package.

What is a C plus plus program to demonstrate the use of access specifiers?
Access specifiers apply to class and struct data types only. If a member is declared before an access specifier is declared, the default access is implied. Once an access specifier is declared, that specifier remains in force until another specifier is declared. Specifiers can be declared in any order and may be repeated as often as required. The following demonstrates usage and purpose of each specifier. class X { friend void f(); // Friends can be declared anywhere. private: // The default access specifier for class types (implied if omitted). int a; // Only accessible to members of X and to friends of X. protected: int b; // Same as private, also accessible to derivatives of X. public: int c; // Accessible to any code where X is visible. }; struct Y { friend void f(); // Friends can be declared anywhere. public: // The default access specifier for struct types (implied if omitted). int a; // Accessible to any code where Y is visible. protected: int b; // Same as private, also accessible to derivatives of Y. private: int c; // Only accessible to members of Y and friends of Y. }; struct Z : X {}; void f() { X x; x.a = 42; // OK! X::a is private and f is a friend of X. x.b = 42; // OK! X::b is protected and f is a friend of X. x.c = 42; // OK! X::c is public and X is visible to f. Y y; y.a = 42; // OK!

Z::Y::c is private and f is a friend of Y. } int main() { X x; x.a = 42; // error! X::a is private and main is not a friend of X. x.b = 42; // error!

What are the access control specifiers used in c plus plus?
The access control specifiers in C++ are...public - to denote that the member is accessible from any in scope codeprivate - to denote that the member is accessible only from within the containing classprotected - the same as private, except that derived classes are includedPrivate is the default for a class type object, while public is the default for a structure type object.

No extern keyword in Java.
What is meant by private access in c plus plus?
It isn't. Private is the default access for class members. For struct members, the default access is public. Aside from default access, a class and a struct serve the same purpose; to define a class. As such, the following class definitions are equivalent: class X { int a; }; struct Y { private: int b; }; Typically, we use a struct to define simple data types with trivial construction and use class for more complex data types, often to encapsulate an invariant or to acquire a resource, hiding the implementation details from consumers using private access.
