Modifiers in Java

Modifiers In Java

In Java, access modifiers are used to set the visibility of the classes, attributes, methods, etc. We can divide modifiers into two groups:

• Access Modifiers: It controls the access level
• Non- Access Modifiers: It doesn’t control access level but provides other functionality.

Access Modifiers

For classes:

Modifier	Description
public	The class is accessible by other class.
default	The class is accessible by other class in the same package.

For properties and methods:

Modifier	Description
public	Accessible by other class.
default	Accessible by other class in the same package.
private	Accessible within the same class.
protected	Accessible within a package and subclass.

Non- Access Modifiers

For classes:

Modifier	Description
final	The class cannot be inherited by other classes.
abstract	The class cannot be used to create objects.

For properties and methods:

Modifier	Description
final	Properties and methods cannot be overridden/ modified.
static	Properties and methods belong to a class rather than an object.
abstract	Can be used in the abstract class and can only be used on methods.
