public: Anyone can access.
private: Only inside the same class.
protected: Inside the same package or by child classes.
(default): Only within the same package.

5. How is an interface different from an abstract class in Java?

Ans:

An interface only has method declarations and is used to set rules for other classes.
An abstract class can have both complete and incomplete methods.
Use an interface when you just want to define behaviors and an abstract class when you want to share some code.

6. How does Java handle errors using exceptions?

Ans:

Java uses a system called exception handling to deal with errors. If something goes wrong, Java throws an exception. Try, catch and finally blocks will be used to handle these problems and maintain program functionality.

7. What is the difference between checked and unchecked exceptions?

Ans:

Checked exceptions are checked at compile-time. You must handle them.
Unchecked exceptions happen during the program run. Handling them is optional.

Ans:

It’s a set of classes and interfaces in Java used to store and manage groups of data like lists, sets and maps. It helps in working with large amounts of data easily.

9. What is a Stream in Java?

Ans:

A Java Stream is a tool used to process data in a functional way. You can use it to filter, sort or perform actions on data without changing the original data.

10. What is garbage collection in Java?

Ans:

Cleaning up memory is done by garbage collection. Java keeps the program quick and effective by automatically deleting items from memory when they are no longer needed.

1. What are main characteristics of Java?

Ans:

Java is simple, object-oriented, secure, and platform-independent. It provides automatic memory management, supports multithreading, and comes with a rich standard library.

2. How is JDK, JRE and JVM different from each other?

Encapsulation: Keeping data safe by hiding details.
Inheritance: One class can use features of another.
Polymorphism: Same thing behaves differently in different situations.
Abstraction: Showing only important details, hiding the rest.

4. What distinguishes Java's "==" from "equals()"?

Ans:

"==" determines if two references are pointing to the same thing.
equals() determines whether the value or content of two objects is the same.

5. What is a constructor in Java?

Ans:

A constructor is a special method used to create and initialize objects. It runs automatically when an object is instantiated.

6. What’s the difference between method overloading and method overriding?

Ans:

Overloading: Same method name with different parameters in the same class.
Overriding: The parent class methods behavior can be altered by using the same method name and parameters in a subclass.

7. What does the static keyword mean in Java?

Ans:

Static means something belongs to the class, not objects. For example, a static method can be called without creating an object.

8. How is an interface different from an abstract class?

Ans:

Interface: Only contains method declarations. A class can use multiple interfaces.
Abstract class: Can have both method declarations and actual method code. A class can only extend one abstract class.

9. What are exceptions in Java and how do we handle them?

Ans:

Exceptions are unexpected events or errors that occur during program execution. They are managed using try-catch-finally blocks to prevent the program from crashing.

10. What’s the difference between a process and a thread?

Ans:

Process: A separate running program.
Thread: A small part inside a process that does a task. One process can have many threads doing work together.

1. How are Java and C++ different from each other?

Ans:

Java works on any device that has a Java program, while C++ works directly on the system it's written for. Java manages memory by itself, but in C++, the programmer has to take care of memory manually.

2. What does encapsulation mean in Java?

Ans:

Encapsulation means keeping the details of how something works hidden. In Java, this is done by putting data and actions together and only letting outside parts see what they need to.

3. What is inheritance in Java? Can you give a simple idea?

Ans:

Inheritance means one thing can get features from another. For example, if a general class is “Vehicle,” a “Car” can inherit from it and use its basic features, like moving or stopping.

4. How does Java take care of memory?

Ans:

Java automatically removes things from memory when they're no longer needed. This helps the program run smoothly without the developer needing to clear memory manually.

5. What does polymorphism mean in Java?

Ans:

Polymorphism means that one action can behave in different ways. In Java, it allows different objects to respond to the same instruction in their own way.

6. Why is the “this” word used in Java?

Ans:

The word “this” is used when Java needs to make it clear that it’s talking about the current object. It's like saying “me” when talking about yourself.

7. How does Java deal with errors or problems during the program?

Ans:

Java has a way to catch and manage errors so the program doesn't crash suddenly. It lets the programmer handle the problem and keep the program running smoothly.

8. What’s the difference between throw and throws in Java?

Ans:

“Throw” is used when you actually cause a problem to be noticed in the program. “Throws” is used to say that a method might cause a problem and the programmer should be ready for it.

9. What is synchronization in Java?

Ans:

Synchronization is like putting a lock on a shared item so only one person can use it at a time. It assists in preventing errors when several jobs attempt to alter the same thing independently.

10. Why is HashSet used in Java?

Ans:

Items are stored using a hash set which prevents repeating the iteams. Its similar to the basket where every item is different and the arrangement doesn't matter.

1. What are the Java's primary features?

Ans:

Java is easy to learn, platform-independent, secure, object-oriented, supports multithreading and has automatic memory management.

2. What are the basic OOP ideas used in Java?
