Add negative keywords like “programming” or “Javascript”
Add the negative keyword ‘Java’ to the ad group so that the ad will stop appearing on JavaScript sites

Only exclude the irrelevant sites that do not directly mention Java coffee that are appearing in the Placement Performance Report

Explanation:
A type of keyword that prevents your ad from being triggered by a certain word or phrase. It tells Google not to show your ad to anyone who is searching for that phrase.
For example, when you add “free” as a negative keyword to your campaign or ad group, you tell AdWords not to show your ad for any search containing the term “free.” On the Display Network, your ad is less likely to appear on a site when your negative keywords match the site’s content.
