151 suggestions for improving java programs-Note 1, java151-Note I. common methods and guidelines for Java Development 1. do not contain confusing letters in constants and variables. Eg: long I = 1l. Is this 11 or lL? We recommend that you use uppercase letters; 2. Do not change constants into variables. Eg: public sta

the concurrency execution condition. When all the test functions that need to be executed in parallel are inventoried and blocked, the command program executes all or part of the code that follows the statement T.parallel () in the function test according to the value of the -parallel tag.The default value of the -parallel tag is the value set by the function Gomaxprocs of the standard library's code package runtime . The function is to set the maximum number of concurrent processing for the go

For the MCU to arm of the students, the RTC may be less contact. Referring to the real-time clock, more often think of is DS1302. Of course, in the STM32, a CPU is enough, do not need to DS1302.In fact, RTC is just a timer, all the information is lost after power-down, so we need to find a place to store this information, so we find the backup register. Because it can still be powered by a button battery after power-down, this data can be saved at all times. We will detail the RTC principles and

This is a creation in Article, where the information may have evolved or changed. 6. Program Testing and documentation 6.1 Program Testing The Go Test command is available in the goes language, which not only tests the code package, but also tests individual source files, as long as there are test source files for those tests. In addition, the go language provides a code package testingfor testing in the standard library, which provides everything you need to write test source files.

to make conditional judgments. The statement that satisfies the condition is executed if the condition is met. The IF and if () are different here:if() is the control flow function: If the statement that represents the condition is judged ... The two are not the same. SetA=0; End if; ifB is NULL Then SetB=0;//SetAssignment Statement ... Simple statements can be followed by complex functions ...End if; SetC=A+b; SelectC as sum; /*return C; This will produce an error ...*/ End;

DOM note (10): JavaScript Regular Expression and dom Regular Expression 1. RegExp ECMAScript supports regular expressions through the RegExp type class. The syntax is similar to Perl: Var exp =/pattern/flags; The patternb part is any simple or complex regular expression. flags is one or more of the symbols carried by each regular expression. Regular Expression

for the maximum matching algorithm of the binary graph-Hungarian algorithm, is plainly the maximum flow algorithm, but it is based on the characteristics of the problem of binary graph, the maximum flow algorithm is simplified, Increased efficiency. Of course we can still use the traditional maximum flow algorithm. At this point, you need to add a source point S and a meeting point T, the capacity is set to 1. Edge for S to left L sets the edge o

Java Learning Note 10--EnumerationBefore JDK1.5, Java could have two ways of defining new types: Classes and interfaces. For most object-oriented programming, these two methods seem to be sufficient, but in some special cases, these methods are not appropriate. For example, to define a color class, which can only have red, Green, blue three values, and any other value is illegal, then JDK1.5 can construct s
