Why protected can be access in same Package without inheritance in java?
java, protected
Solution
Why? Because that's how the Java programming language was designed. There's not much more to it.
Something that is `protected` is accessible from
- the class itself,
- classes in the same package (doesn't matter if they are subclasses or not),
- subclasses (doesn't matter if they are in the same package or not).
This is different from C++, but Java is not C++, so it doesn't necessarily work in the same way.
