　The basic types of integers in Java are Byte,short,int,long, 1, 2, 4, 8 bytes in size, and a byte size of 8 bits, which is 8 binary codes (0/1).The binary code in the computer is divided into the original code, the inverse code, the complement. The number in the computer is stored in the original code, and negative numbers are stored in twos.The original code is in the form represented in the machine, the first 1 represents a negative number, and 0 r

answer in a technical post.If you define an anonymous inner class, and you want it to use an object that is set externally, the compiler requires its argument referenceis final. By research, the Java Virtual machine is implemented in such a way that the compiler detects whether there is a direct use of externalWhen you define a variable, you define a variable of the same type if you have access, and then give yourself an external variable in the cons

Leetcode reverse Integer, because the maximum value of int is 2 minus one, and the minimum value is 31 times of 2.My first code put the res recursively in the try and thought there would be an exception to the overflow, but not.Because the arguments that are passed in are of type int, and the memory and time requirements are met, long is sufficient to store the intermediate result.
