Prompt Solr Query using SolrJ - solr

Question

I am trying to structure a solr query using solrj. From my understanding of Solr-7.5.0 all libraries and dependencies for solrj should be included in my solr installation. Below is my /dist folder followed by my /dist/solrj-lib folder
Now, my query will be tied to an html post form but I want to get the solrj working first. Here is the entirety of my solrj
import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.SolrQuery;
import org.apache.solr.client.solrj.HttpSolrClient;
String queryInput = q;
SolrQuery query = new SolrQuery(queryInput);
SolrClient client = new HttpSolrClient.Builder (
"http://localhost:8983/solr/sqltest")
.build();
QueryResponse response = client.query(query);
SolrDocumentList list = response.getResults();
This will not compile because it does not recognize my classes (SolrClient, SolrQuery, etc). I am sure there are countless issues right now but Im not sure where to start.
As a side question, I was looking into other APIs that are not in compiled code. Would one of these be better used for a web application or is it safe to use solrs native solrj?

You can safely use SolrJ - in fact, if you're writing a Java application, it's the recommended way of interacting with Solr. See Using SolrJ - Building and Running SolrJ Applications for further details than what I've given below.
I've assumed you're on Windows from your screenshots - if you're on Linux or OS X, replace ; with : as the path separator below.
To include the SolrJ jar, you need to include a -classpath ".;path-to-solr-solrj-7.5.0.jar argument when running javac. This is the only jar required to compile your application.
When running it you'll have to include the jars found in the solrj-lib path. You can do this by including a class path argument to java with your files. Use java -classpath ".;path-to-solrj-lib\* to include all the jar files in the directory.
