An Access Modifier is a key word in java that determines what level of access or visibility a particular java variable/method or class has. There are 4 basic access modifiers in java. They are:
1. Public
2. Protected
3. Default and
4. Private
Private is the most restrictive access modifier whereas public is the least restrictive. Default is the access protection you get when you do not specifically mention an access modifier to be used for a java object.
Java programming does not run by just a single piece of class that has the whole functionality. You have hundreds of classes that interact with one another, passing data between them and returning output to the user of the system. So it is very important for members of one class to access members of another. Here members may refer to variables, methods and even classes. So, this is where the access modifiers come into picture. The modifier associated with every member of the class determines what level of visibility that member has.
Public Members:
If a variable or method is declared public, it means that it can be accessed by anyone or any other class (irrespective of which package they are in). Of course, it is mandatory that the class inside which the public method is placed is visible in the first place for the method or variable to be visible. You can check out the code example in the previous paragraph for an example. The method from Dad class is visible and available for usage inside the son class.
For a subclass, if a member of its superclass is declared public, the subclass inherits that member regardless of whether both classes are in the same package.
Ex:
package pack1;
public class Parent {
public String getName() {
return "Parent";
}
}
Package pack2;
Import pack1.Parent;
Public class Child extends Parent{
Public String getParentsName() {
return getName();
}
}
If you see the example above, the child class is able to access the parent class's method getName() even without instantiating an object of the parent because it inherits the Parent class and all its method as part of the inheritance (extends) feature.

Where do you define the access specifier for a java method properties?
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.
What is an access specifier do?
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.
Default access specifier in java?
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'.

What is meant by default access of class in java?
That's what you get when you don't include any access specifier, such as "public" or "private". This default access gives access to any class in the same package.
What is the difference between access specifier and access modifier?
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.
Do you get Security by access specifiers in Java?
No, because there is no such thing as an access specifier in Java. There are access modifiers, and security is their entire purpose, so of course you get it when you use them.
Explain the significance of public and protected and private access specifiers in inheritance?
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.
Why java is secured compare with other language?
Because there is an access specifier called private in java by which security can be provided
