Map and set are used in projects for efficient data storage and retrieval.

• Map is used to store key-value pairs, allowing quick access to values based on their keys.

• Set is used to store unique values, ensuring that each value is only stored once.

• Map and set are commonly used in data processing, caching, and indexing operations.

• Example: In a project, a map can be used to store user preferences with keys representing the preference names and values representing the corresponding...read more

XPath and CSS are both locator strategies used in web testing to identify elements on a webpage.

• XPath is a language used to navigate XML documents and is commonly used in web testing to locate elements based on their attributes or structure.

• CSS selectors are used to select elements based on their attributes, classes, or IDs.

• XPath is more powerful and flexible than CSS selectors, but can be slower.

• CSS selectors are generally faster and easier to read and write.

• XPath can traver...read more

Different locators are used in software testing to identify and interact with elements on a web page or application.

• XPath: Uses path expressions to navigate through elements in an XML document

• CSS Selector: Selects elements based on their attributes, classes, or IDs

• ID: Locates elements by their unique identifier

• Name: Finds elements by their name attribute

• Class Name: Identifies elements by their class attribute

• Tag Name: Locates elements by their HTML tag name

• Link Text: Finds el...read more

HashMap is a data structure in Java that stores key-value pairs and allows for fast retrieval of values based on keys.

• HashMap is part of the Java Collections framework.

• It uses hashing to store and retrieve elements efficiently.

• Each key in a HashMap must be unique.

• Example: HashMap map = new HashMap<>(); map.put("apple", 5); int value = map.get("apple");

STATIC vs FINAL - STATIC is used to define a class-level variable or method that can be accessed without creating an instance of the class. FINAL is used to define constants or prevent inheritance or method overriding.

• STATIC variables and methods belong to the class itself, while FINAL variables cannot be changed once initialized.

• STATIC variables are shared among all instances of a class, while FINAL variables are unique to each instance.

• STATIC methods can be called without c...read more
