##The more difficult part in this video is the Java image Scaled thumbnails:

In current web projects, there are more and more pictures, and the size of the pictures is also getting larger and larger, which can easily reach 1M, 2M, or even larger. Images uploaded by users generally cannot be used directly. Generally, two or three corresponding thumbnail images need to be generated to adapt to different terminals and different scenarios. For example, PC, mobile phone, tablet and other different terminals; for example, in the picture list and picture details, one must use thumbnails and the other must use high-definition pictures.

The first step in general image optimization is to use thumbnails in appropriate places, and try not to use CSS to scale high-definition original images on the web. The following analyzes the technology of how to generate different thumbnails in Java.
