What is the callback mechanism? Summary of usage examples of callback mechanism

This article mainly introduces the relevant information about the detailed explanation of java callback mechanism examples. Friends who need it can refer to the detailed explanation of java callback mechanism examples. I didn’t understand what callbacks were before. I heard people talking about adding a callback method every day, and I thought to myself. Damn, what is a callback method? Then I searched and searched on the Internet.
