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. For interface members (fields and methods), the default access is public..
In this manner, what is default access specifier in java?
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 is accessible only by classes in the same package. The default modifier is not used for fields and methods within an interface.
Likewise, what is an access modifier in Java? A Java access modifier specifies which classes can access a given class and its fields, constructors and methods. Access modifiers can be specified separately for a class, its constructors, fields and methods. Classes, fields, constructors and methods can have one of four different Java access modifiers: private.
Regarding this, what is the default access modifier in Java class?
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).
What is default data type in Java?
Its minimum value is - 2,147,483,648and maximum value is 2,147,483,647. Its default value is 0. The int data type is generally used as a default data type for integral values unless if there is no problem about memory. Example: int a = 100000, int b = -200000.

What is constructor in OOP?
A constructor is a special method of a class or structure in object-oriented programming that initializes an object of that type. A constructor is an instance method that usually has the same name as the class, and can be used to set the values of the members of an object, either to default or to user-defined values.What is an interface?
An interface is a reference type in Java. It is similar to class. It is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface. Along with abstract methods, an interface may also contain constants, default methods, static methods, and nested types.Is default a keyword in Java?

Answer: We can not declare top level class as private. Java allows only public and default modifier for top level classes in java. Inner classes can be private.How can you achieve runtime polymorphism in Java?
We can perform polymorphism in java by method overloading and method overriding. Dynamic (run time) polymorphism is the polymorphism existed at run-time. Here, Java compiler does not understand which method is called at compilation time. Only JVM decides which method is called at run-time.What is Polymorphism in Java?
Polymorphism in Java is a concept by which we can perform a single action in different ways. We can perform polymorphism in java by method overloading and method overriding. If you overload a static method in Java, it is the example of compile time polymorphism. Here, we will focus on runtime polymorphism in java.What is super keyword in Java?
super is a keyword. It is used inside a sub-class method definition to call a method defined in the super class. Private methods of the super-class cannot be called. Only public and protected methods can be called by the super keyword. It is also used by class constructors to invoke constructors of its parent class.Are class members public by default?
In C++, a class defined with the class keyword has private members and base classes by default. A structure is a class defined with the struct keyword. Its members and base classes are public by default. In practice, structs are typically reserved for data without functions.What is keyword auto for?
auto: This is the default storage class for all the variables declared inside a function or a block. Hence, the keyword auto is rarely used while writing programs in C language. Auto variables can be only accessed within the block/function they have been declared and not outside them (which defines their scope).What is rule of accessibility in Java?
Java has for level of accessibility: Default: Without defining access modifier for method. These methods can be accessed from within class and package. Private: These methods can be accessed from within class only. Protected: These methods can be accessed from class, subclass and package only.What are class access modifiers?
Access modifiers (or access specifiers) are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. A class cannot be declared as private.What is static keyword in Java?
The static keyword in Java is used mainly for memory management. It is used with variables, methods, blocks and nested classes. It is a keyword that is used to share the same variable or method of a given class. This is used for a constant variable or a method that is the same for every instance of a class.Can a class be private or protected in Java?
Protected class member (method or variable) is just like package-private (default visibility), except that it also can be accessed from subclasses. Since there's no such concept as 'subpackage' or 'package-inheritance' in Java, declaring class protected or package-private would be the same thing.Can we override protected method in Java?
Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.What are the different types of access modifiers?
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.

What is private public protected in Java?
