Fix Error with git even after adding the public key. Git bash Permission denied (publickey).

This could be a common issue while using git bash in windows.

Before fixing this issue, it is assumed that the public/private key pair is generated and the public key is configured in the git server (github, bitbucket or whatever).

Still, if you get the "Permission denied (publickey)." which means, the ssh agent might not have recognized your key. To solve this you'll have to make sure the ssh agent is running and the key is added.

Run the ssh agent, execute the below command in git bash

exec ssh-agent bash

To check if the key is added run the below command.

ssh-add -l

If there is no key, it will print "The agent has no identities."

To add the key, run the below command with the path to your private key.

ssh-add ~/.ssh/thilinarsa

(My key file is located in C:/User/Thilina/.ssh/thilinarsa)

If you run the ssh-add -l command again you should see the key file added.

Run the git clone or pull command again and see if it works!

Java, how to create a list with a single element

I wanted to create a Java List with a single element. Yet, I wanted to add more elements later. So, I was looking for a couple of ways to do this. So far there are multiple elegant ways to create a list with a single element with a one-liner. Not so much for a modifiable list though. Here's what I gathered so far. Followings are a few ways of creating a list with strictly a single entry. Can't add more elements. 1. Collections.singletonList() This returns an immutable list that cannot be modified or add more elements. // An immutable list containing only the specified object. List<String> oneEntryList = Collections. singletonList ( "one" ) ; oneEntryList.add( "two" ) ; // throws UnsupportedOperationException 2. Arrays.asList() This returns a fixed-size list consisting of the number of elements provided as arguments. The number of elements provided would be an array hence the size is fixed to the length of the array. // Returns a fixed-size list List...
