VS code cannot read java file

Question

I am running java spring boot in VSCode IDE , but if I edit something while running VSCode give an error "Unresolved compilation[Screenshot of the error][1]".

I think the IDE cannot read the java file after modification.

Someone can tell me why is it happening ? [1]: [https://i.stack.imgur.com/bw3s8.png][1]

Your question is vague but it sounds like you haven't installed the necessary plugins. Here's the documentation for setting up VS Code for Java.

UPDATE: Looking at the screenshot in your updated question, you can find the answer in this post. Basically the DatatypeConverter class is not part of the JDK Java 9 onwards.

Thank you so much for that @steven35. Do you know what specific plugins should I install ? – stranger_cool Sep 02 '19 at 11:06
Java extension pack is a good place to start. https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-pack – steven35 Sep 02 '19 at 11:09
