What is the usage of thumbnails in Java?

In Java, thumbnails are commonly used to represent a smaller version of the original image. These smaller images are typically displayed in the UI to reduce loading times and save space. In Java, you can use the Image class or third-party libraries to generate and manipulate thumbnails. By specifying the size and quality parameters of the thumbnail, you can easily create different sizes and qualities as needed. The process of generating thumbnails typically involves reading the original image, resizing it, and then saving it as a new image file or using it in memory.
