Short S = 1; S = S + 1; CompilationFailedShort S = 1; S + = 1; why can I compilePassSo? Another problem is that implicit type conversion can be automatically converted from small to large, that is, byte-> short-> int-> long. If the precision is lost in turn, it must be performed.Display type conversionS + =

permissioned setting, but his communication is at least squared, and obviously is hard to support large network nodes, even in permissioned setting. According to colleague Test, the Hyperledger 100 nodes are about to finish the egg ... PBFT is the abbreviation of practical Byzantine Fault tolerance, which means a practical Byzantine fault-tolerant algorithm. This algorithm is proposed by Miguel Castro (Castro) and Barbara Liskov (Liskov) in 1999, which solves the problem of inefficient origin

There are many formulas in the history of Pi Pai, in which Gregory and Leibniz found the following formula:Pai = 1-1/3+1/5-1/7 (...)This formula is simple and graceful, but in the ointment, it converges too slowly.If we rounded up the two decimal places that kept it, then:Accumulated

When writing a pom.xml file in eclipse today, the Chinese in the note was identified by Eclipse as error: Invalid byte 1 of 1-byte UTF-8 sequence, which has been encountered many times, the root cause of the problem is: The cause of this is a file which is not UTF-8 is being parsed as UTF-8. It is likely, the parser is encountering a, a byte value in the range FE - FF . These values is invalid in

At first, the computer operating system was 32 bits, and the time was expressed as 32 bits.System. Out. println (integer. max_value );2147483647Integer is represented by 32 bits in Java, so the maximum value expressed by 32 bits is 2147483647. In addition, the total number of seconds for the second day of the year is 365,2147483647/31536000 = 68.1That is to say, the maximum time that 32 bits can represent is 68 years. In fact, by, January 1, January 1

Why add the where 1=1 to the back of the SQL statement and really wonder about the children's shoes that were first seen. It is felt that the select * from table1 where 1=1 is completely indistinguishable from the select * from table1. In fact, this idea is wrong. Remember that the "existence is reasonable" Regardless
