use of public access specifier is
we can access the class members(methods,variables) out side the class using class reference
There is no such thing as an access specifier in Java. There are access modifiers. They specify the access level of the item they modify: public, private, protected.
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.
We define the access specifier of a function at the place of its method signature(The place we write the method's name).for example,public void sample(){}here "public" is the access specifier of function name-sample.
Three types of access specifier private , public ,protected
There are no access specifiers in C. All functions and data are public.
There is no such thing as an access specifier in Java. There are access modifiers.The default access modifier if unspecified is to allow access to classes in the current package only, except within an interface where the default is 'public'.

These are all access modifiers in Java. a. Public - these are accessible anywhere. This is the least restrictive access specifier. b. Private - these are accessible only inside the declaring class. This is the most restrictive access specifier. c. Protected - these are in between public and private. These are accessible to all classes that inherit this class d. Package - this is the default access specifier. These are accessible to all classes that are present in the same package as the contained class.
An access specifier is a keyword applied to a variable, or method, which indicates which parts of the program are permitted to access it.
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.
An access modifier is another name for an access specifier, which in object-orientated software is a keyword applied to a variable which indicates which other parts of the programme are permitted to access it.
