increment java integer

I have been searching for it online for a long time. Some people say that uuid is better, that is, it is easier to merge data into sub-databases and sub-tables, and some people say that auto-increment is better, when there is more data in the table,

Like C, Java provides a rich shortcut for computing. These shortcuts can make the code more refreshing, easier to input, and easier for readers to read.Two good shortcuts are the increment and decrement operators (often referred to as "AutoIncrement"

Java has designed classes for numeric security counters under multithreading, these classes are called atomic classes, and some of them are as follows:

Almost all operators can only operate on Primitives ). The exceptions are "=", "=", and "! = ", They can operate on all objects. In addition, the String class supports "+" and "+ = ". (1) Assignment If "A = B" is used for the primary type, the
