Question

Accepted Answer

The question covers Java programming concepts, software testing methodologies, and test scenarios vs test cases.

To print the number of vowels in a word, iterate through the characters of the word and count the vowels (a, e, i, o, u).
To reverse a string, iterate through the characters of the string in reverse order and append them to a new string.
To print each word only once from a sentence, split the sentence into words, store them in a set to remove duplicates, and then print each word.
For Indigo page placeholder comparison validation, compare the 'From' and 'To' placeholders on the page to ensure they match.
STLC lifecycle stands for Software Testing Life Cycle, which includes phases like requirement analysis, test planning, test design, test execution, and test closure.
Sanity testing is a subset of regression testing to quickly check if the software is working after minor changes, while smoke testing is a preliminary test to check if the software build is stable.
End-to-end testing involves testing the entire application flow from start to finish to ensure all components work together correctly.
Test scenarios are high-level descriptions of what to test, while test cases are detailed steps to execute a test scenario.
