和C 类似,Java 提供了丰富的快捷运算。这些快捷运算使编码更方便,同时也使得代码更 容易阅读,但是有时可能使代码阅读起来更困难。 递增和递减运算是两种相当不错的快捷运算(常称作“自动递增”和“自动递减”运算)。其中, 递减操作符是“--”,意为“减少一个单位”;递增操作符是“++”,意为“增加一个单位”...

This will increment the value ofcounterby 5. Similarly, we can useDECRto decrement the value of a key. Expiring keys in Redis Redis allows us to set an expiration time for keys. Once a key expires, it is automatically deleted from Redis. This feature is useful for implementing caching or...
