Yes, we can use the default access modifier with Java classes. When no access modifier is specified for a class, it is given the default access modifier by default.
The key points about using the default access modifier with classes in Java are:
Default Access Modifier for Classes
- If a class has no access modifier specified, it is given the default access modifier.
- Classes with the default access modifier can only be accessed from within the same package. They are not accessible from outside the package.
- You can use the default access modifier with top-level classes and nested classes.
- Top-level classes can only be declared as public or default. They cannot be declared as private or protected.
Example
// File: MyClass.java
class MyClass {
// class members
}In this example, the MyClass has no access modifier specified, so it is given the default access modifier. It can only be accessed from other classes in the same package.
// File: AnotherClass.java
package some.other.package;
import com.example.MyClass; // Compile error: MyClass is not public
public class AnotherClass {
MyClass obj; // Compile error: MyClass is not accessible
}In this example, trying to access MyClass from another package results in a compile error because MyClass has default access and is not accessible outside its package.
So in summary, yes, you can use the default access modifier with Java classes. It makes the class accessible only within the same package and not from outside the package.
