Basics of Java Part 2

Image
  11.  Exception Handling :     Exception handling in Java allows you to handle runtime errors gracefully. It involves try, catch, finally, and throw keywords. 12.  Packages :     Packages are namespaces that organize classes and interfaces into a hierarchical structure. They help in organizing and managing large-scale Java applications. 13.  Modifiers :     Modifiers are keywords that define the access levels, scope, and behavior of classes, methods, and variables. Examples include public, private, protected, static, etc. 14.  Constructors :     Constructors are special methods used for initializing objects. They have the same name as the class and are called when an object is created. 15.  Methods Overloading and Overriding :     Overloading is the ability to define multiple methods with the same name but different parameters in the same class. Overriding involves redefining a method in a subclass with the...

Basic Java Interview Questions

Image
21. Question: What is the purpose of the 'interface' keyword in Java?      Answer: The 'interface' keyword in Java is used to declare a collection of abstract methods that can be implemented by classes. It provides a way to achieve multiple inheritances and define a contract for implementing classes.   22. Question: How does the 'StringBuilder' class differ from 'StringBuffer' in Java?      Answer: Both 'StringBuilder' and 'StringBuffer' are used for string manipulation, but 'StringBuilder' is not synchronized, making it more efficient in a single-threaded environment, whereas 'StringBuffer' is synchronized, ensuring thread safety in a multi-threaded environment.   23. Question: What is the purpose of the 'transient' keyword in Java?      Answer: The 'transient' keyword in Java is used to indicate that a variable should not be serialized during object serialization. It is often used for sensitive informatio...

  Certainly! Here are 10 more machine learning interview questions along with their answers in regards to previous LinkedIn post: Certainly! Here are 10 more machine learning interview questions along with their answers: 21. Explain the concept of Support Vector Machines (SVM).     - Answer: Support Vector Machines are supervised learning models used for classification and regression tasks. SVM finds a hyperplane that best separates different classes by maximizing the margin between them. 22.   What is the purpose of the F1 score?       -  Answer:  The F1 score is the harmonic mean of precision and recall. It provides a balance between precision and recall, making it a useful metric when the class distribution is imbalanced. 23.   Describe the concept of Cross-Entropy in the context of Neural Networks.       -  Answer:  Cross-Entropy is a loss function used in neural networks for classificatio...
