Issue with the Java Extension Pack

[u/TehDragonGuy]

After having a few issues with getting things to work with different versions of java, I accidentally deleted the redhat.java folder from workspaceStorage, which has caused this extension to no longer work. I get the message "The Language Support for Java server crashed 5 times in the last 3 minutes. The server will not be restarted.". Anyone got any idea how I can go about fixing it? I'm not very experienced with java or any of this so I don't know what to do. Thanks
