Answer In Java, a package is a way of organizing related classes and interfaces into a single namespace, while a library is a collection of related packages, classes, and interfaces that provide some functionality to a Java
Related Topics JAVA Programming Question 8 What is the use of the static import keyword in Java and when is it applied? Answer The static import keyword in Java allows you to access static members (fields and methods) of a class without having to prefix them with the class name. It is used to make
Related Topics Data Science Question 34 What is the difference between sensitivity and specificity? Answer Sensitivity and specificity are measures used to evaluate the performance of a binary classification model. Sensitivity, also known as recall, is the proportion of true positive cases (i.e., the number of correctly identified positive cases) out of the total number
Related Topics Data Science Question 31 What is the ROC curve and why is it important? Answer Introduction: The ROC (Receiver Operating Characteristic) curve is a graphical representation of the performance of a binary classifier, which plots the true positive rate (TPR) against the false positive rate (FPR) at different classification thresholds. The TPR (also
Related Topics Data Science Question 28 What is cross-validation and how is it used in model evaluation? Answer Introduction: Cross-validation is a technique used in model evaluation to estimate the performance of a machine learning model on new and unseen data. The idea behind cross-validation is to partition the available data into training and validation
Related Topics Data Science Question 25 What is the difference between reinforcement learning and supervised learning? Answer Reinforcement learning and supervised learning are two different approaches to machine learning. Supervised learning is a type of machine learning where the algorithm is trained on labeled data. The training data consists of input features and corresponding output
