Interview Questions to Ask Java Developers

1. What is the Java Virtual Machine (JVM), and how does it work?

-The Java Virtual Machine (JVM) is an abstract computing machine that enables a computer to run a Java program. The JVM executes Java bytecode, which is a compiled form of Java source code, and provides a runtime environment for the execution of the bytecode. It is responsible for allocating memory and managing the memory heap, as well as handling security and thread management.

2. What is the difference between an interface and an abstract class in Java?

-An interface in Java is a type that defines a set of abstract methods that a class must implement. It is used to specify the behavior of a class without implementing the actual code for the methods. An abstract class, on the other hand, is a class that cannot be instantiated and is typically used as a base class from which other classes can inherit. An abstract class can have both abstract and non-abstract (concrete) methods, whereas an interface can only have abstract methods.

3. What is the difference between a constructor and a method in Java?

-A constructor in Java is a special method that is called when an object is instantiated. It is used to initialize the state of an object by setting the values of its instance variables. A constructor has the same name as the class and does not have a return type. A method, on the other hand, is a regular member function of a class that has a return type and can be called on an object. A method can perform any operation on the object’s state, such as setting or getting the value of its instance variables.

4. What is the difference between a static method and a non-static method in Java?

-A static method in Java is a method that belongs to the class itself, rather than to an instance of the class. It can be called on the class itself, without the need to create an object. A non-static method, on the other hand, is a method that belongs to an instance of a class and can be called on an object. Non-static methods have access to the object’s state, including its instance variables, whereas static methods do not have access to the object’s state.

5. Can you explain the concept of inheritance in Java?

-Inheritance in Java is the mechanism by which a class can inherit the properties and behaviors of another class. It allows a subclass to reuse the code and behavior of a superclass, while also adding its own unique characteristics. This enables code reuse and modularity, as well as facilitating the creation of hierarchical classifications.
