Top 11 GIT Interview question for Automation Testing/SDET/Lead QA?

1. How to create repository in GIT?

    $ git init

2. How to clone a repo?

Clone the test repo into a new directory called TEST:
$ git clone https://github.com/<username>/test.git TEST

3. How to switch branch?
 git switch branchname

4.  How to unstage changes or restore files?

 Maybe you accidentally staged some files that you don't want to commit.
 $ git restore test.js
 $ git restore .

 5. How to undo commits?

 The following command will undo your most recent commit and put those changes back into staging, so you don't lose any work:
$ git reset --soft HEAD~1
The next one will completely delete the commit and throw away any changes. Be absolutely sure this is what you want:
$ git reset --hard HEAD~1

6. How to undo last push?

Some would say this is bad practice. Once you push something you shouldn't overwrite those changes. Instead, you're supposed to create a new commit that reverts the changes in the last one. So, technically, you shouldn't do this, but... you can?

$ git reset --hard HEAD~1 && git push -f origin master

7. How to fetch changes from both origin and upstream?

$ git fetch --multiple origin upstream

8. How to delete a local branch?

$ git branch -d <local_branch>
Use the -D option flag to force it.

9. How to stash ur chnages?

$ git stash


10.  How to push changes?

 git add -all
 git commit -m "message"
 git push remote_server branch_Name

11. Difference between rebase and merge?
 git merge apply all unique commits from branch A into branch B in one commit 
 git rebase gets all unique commits from both branches and applies them one by one.
 git rebase rewrites commit history but doesn't create extra commit for merging.

Top 5 differences between Arraylist and Linkedlist? Arraylist vs Linked list? When to use arraylist and linkedlist?Interview question for Automation testing/Core Java?

• LinkedList can be iterated in reverse direction using descendingIterator() but to iterate over the ArrayList in reverse direction we need to write our own code
  
  
• Insertions and Deletions are faster in LinkedList as compared to ArrayList because there is no need of resizing array and copying content to new array if array gets full which makes adding into ArrayList of O(n) in worst case, while adding is O(1) operation in LinkedList in Java. so if we have more add or delete operations then we should go with Linked list.
• LinkedList has more memory overhead as each node holds both data and address of next and previous node but in ArrayList each index only holds actual object or we can say data.
• ArrayList internally uses a dynamic array while LinkedList internally uses a doubly linked list.
• Arraylist get method is faster than Linked list so fetching data or search operations is good in arraylist.
