Java Programming Questions: Top 20 Examples

To Read about Java Interview Questions

Here are some common Java programming questions you might encounter:

1. String Methods:
   • toCharArray
   • length
   • contains
   • equals
2. Array Methods:
   • Arrays.sort
3. List Methods:
   • add
   • get
   • remove
   • contains
   • size
4. Set Methods:
   • add
   • size
   • contains
5. Map Methods:
   • put
   • getOrDefault / get
   • size
   • containsKey

Problem-Solving Approach

Focus on practicing 20 problems using:

• for loop
• for-each loop
• while loop

Avoid memorizing solutions. Instead, practice solving them on paper to reinforce your understanding and improve problem-solving skills.

Theory Questions on OOP Concepts

Providing a four-dimensional answer to each OOP concept showcases your depth of knowledge and understanding:

1. Theory: Explain the concept in detail.
2. Selenium Usage: Example – WebDriver extends SearchContext
3. Project Usage: Example – Testcases extends BaseHooks
4. Java Usage: Example – List extends Collection

Selenium WebDriver Questions:

 

Key Areas to Focus On

1. WebTable: How to handle dynamic web tables effectively.
2. Switch Window Handles: Various methods (e.g., Set -> List -> get, iterator -> next, for-each -> title -> break).
3. XPath Patterns: Using following and sibling.

Additional Learning

• ChromeOptions: Understand and explain its use, enhancing your capability to configure browser settings programmatically.

Framework Questions:

 

Common Framework Explanation

When asked to explain your framework, provide a detailed description of its daily execution process:

1. Jenkins Job/Pipeline:
   • Triggered at 10 PM IST, a Jenkins job or pipeline initiates the process.
   • Git WebHook pulls the latest code to the Jenkins workspace, ensuring the most recent updates are included.
2. Maven Goal (test):
   • The Maven goal ‘test’ calls testng.xml, which organizes and runs the test cases.
   • Executes test cases with TestNG annotations, automating the testing process.
3. Browser Launch:
   • WebDriver initiates the browser, setting the stage for automated testing.
4. Data Handling:
   • Data fetched from XLS files using Apache POI is passed to the Data Provider, ensuring data-driven testing.
5. Test Execution:
   • Each step is reported with snapshots via ExtentReports, providing detailed and visual feedback.
6. Final Reporting:
   • HTML report generated by Jenkins is shared through email, summarizing the test results.

Physical Structure of Framework

• Hooks: Setup and teardown actions.
• Tests: Actual test cases.
• Wrappers: Helper functions and utilities.
• Utils: Common utilities.
• Features: Specific functionalities tested.

By understanding and preparing for these aspects, you can navigate the interview process in service companies with confidence and clarity.
