HPLC is a chromatography technique used to separate, identify, and quantify components in a mixture.
HPLC stands for High-Performance Liquid Chromatography.
It works on the principle of separating components based on their affinity towards the stationary and mobile phases.
The stationary phase is a solid or liquid packed in a column, while the mobile phase is a liquid that flows through the column.
The sample is injected i...

I appeared for an interview in Feb 2025, where I was asked the following questions.
Java provides various classes for file handling, allowing reading and writing operations using streams.
Use FileWriter for writing text files: FileWriter writer = new FileWriter('file.txt');
Use BufferedWriter for efficient writing: BufferedWriter bufferedWriter = new BufferedWriter(writer);
Always close the writer using bufferedWriter.close() to free resources.
Handle exceptions using try-catch blocks to manage IOExceptio
Creating a collection from a string involves splitting the string into elements and storing them in a data structure.
Use the split() method to divide the string into an array. Example: 'a,b,c'.split(',') results in ['a', 'b', 'c'].
Choose a collection type based on requirements: Array, List, Set, etc.
For unique elements, consider using a Set. Example: new Set('aabb') results in ['a', 'b'].
If order matters, use an Array ...
In Java, a top-level class cannot be declared private; only nested classes can be private.
Top-level classes can be public, protected, or package-private, but not private.
Private classes can only be nested within another class.
Example of a private nested class: class Outer { private class Inner {} }
Private classes are used to encapsulate functionality within a specific context.
In Playwright, the alternative for @Test annotation is using the test function from the Playwright Test framework.
Playwright uses the 'test' function to define test cases, similar to @Test in other frameworks.
Example: 'test('should load the homepage', async () => { ... });'
You can group tests using 'describe' blocks: 'describe('Homepage tests', () => { ... });'
Playwright supports various assertions through the 'e...
Assertions in Playwright validate expected outcomes in automated tests, ensuring application behavior meets requirements.
Use 'expect' from Playwright's test library to create assertions.
Example: expect(page.title()).toBe('Expected Title');
Assertions can check various conditions like visibility, text content, and element states.
Example: expect(await page.isVisible('selector')).toBe(true);
Assertions can be chained for mo...
Read command line arguments in Python to execute functions based on user input.
Use the 'sys' module to access command line arguments: `import sys`.
Access arguments via `sys.argv`, which is a list of command line inputs.
Example: `sys.argv[0]` is the script name, `sys.argv[1]` is the first argument.
Define functions and use conditional statements to execute based on input.
Example: `if sys.argv[1] == 'test': run_test_funct
Creating persistent automation involves ensuring scripts run after system restarts using services or scheduled tasks.
Use a service manager (e.g., systemd on Linux) to run automation scripts on startup.
Create a scheduled task in Windows Task Scheduler to trigger automation scripts after reboot.
Implement a watchdog mechanism to restart automation if it fails unexpectedly.
Store automation state in a database or file to re...
