Could not pull from git repository – wrong credentials on windows

I changed my password on the github repository and Intellij asks again for the new credentials. I used the new credentials but it still tells me that I am using wrong credentials. I tried using the old credentials and it still gives me the wrong credentials. I invalidating cache and restarting IntelliJ, but it didn't work and I also tried from windows terminal but it still returns invalid credentials. I tried logging in via the webpage and it works

Fix Java OutOfMemoryError

Problem: For a university project I had to implement a simple Java application that uses the Twitter4J Java library for the Twitter API to collect data (tweets) based on different criteria and then analyze those data and generate statistics. For the data analysis I used the natural language processing toolkit developed by Stanford (called Stanford CoreNLP). The problem was, that the data were too large and when running the NLP algorithms I encountered the OutOfMemoryError. Solution: increase the heap size of the Java virtual machine JVM using the flags -Xmx and -Xms. The flag Xmx specifies the maximum memory allocation pool for a (JVM), while Xms specifies the initial memory allocation pool. How to do this in Intellij? Open the "Run/Debug Configurations" of your application and in the field "VM options" add the flags -Xmx and -Xms with the desired memory amount (e.g. -Xms4g -Xmx8g).

Collaborate working with IntelliJ

Problem: Collaborate working with IntelliJ and Java: my colleagues and I used Java and the IntelliJ IDE for a university project (online voting system). To work together we decided to use git and had the issue, that by default the git Repository was filled with too much build data, because the .idea folder of the IntelliJ project, which contains project specific settings files and per-project details such as VCS mapping and run and debug configurations, as well as per-user details, such as currently open files, navigation history and currently selected configuration. Every commit ran into a conflict, because these files should not be commited to source control. Solution: Add a .gitignore file (also commited to the repository), which is then used by IntelliJ (and git) to determine which files and directories to ignore, before a commit is made.
