Let's explain Java's access modifiers but with a real-world analogy: Public: Imagine a public park. Anyone can come in and use the park, right? In Java, when something is marked as public, it's like this park. Any other part of your program can see and use this public part. It's completely open for all. Private: Now think of your own bedroom in your house. Only you can enter it, right? In Java, when something is private, it's like your bedroom. Only the code within the same class (think of it as the same house) can access this private part. It's not visible or accessible to the outside world. Protected: This one is like your living room at home. Your family and relatives (who live in the same house or are closely related) can come in, but not your neighbors or strangers. In Java, protected is similar. The code in the same class or in a subclass (think of them as family or relatives) can access a protected member, but other unrelated classes (like neighbors) cannot.
