What is the default access modifier for class variable in Java?

The Default access modifier is package-private (i.e DEFAULT) and it is visible only from the same package.23 Nis 2013

Default access modifier means we do not explicitly declare an access modifier for a class, field, method, etc . A variable or method declared without any access control modifier is available to any other class in the same package.6 Şub 2018

For interface members (fields and methods), the default access is public. But note that the interface declaration itself defaults to package private .
