Contrary to the other answers, there are no undefined behavior here, and there are no overflow. Unsigned integers use modulo 2n arithmetic.Section 4.7 Paragraph 2 of the standard says "If the destination type was unsigned, the resulting value is the least unsign Ed integer congruent to the source integer (modulo 2n where n was the number of bits used to represent th e unsigned type). " This dictates that-1 are equal to the largest possible unsigned int (modulo 2n). Section 3.9.1 paragraph 4 says

Recently learning basic Java knowledge, this is one of the most common problems, I would like to list three different methods of outlier, of course, I chose the simplest three kinds:1. You can call the properties and methods of the class that you want to access by using static statics variables. Because characteristics of static in Java : The static variable is initialized when the class is loaded. Static variables for multiple instances share the same block of memory area.
