Today, when using BufferedReader, there was a strange problem.Sometimes the line will be less than one character at the beginning of a newline.The starting code is written like this. while (Br.read ()!=-1 ) { = br.readline (); System.out.println (str); }Problem point:Finding the data found that the original is in the while loop, the written judgment statement Br.read ()!=-1 There is a problem.When the program reads, it reads a br.read () Word to determine if it is the last, and if not,

Mobile phone GPS positioning is slow, high precision, more power consumption, network positioning faster, low precision, less power consumptionWhen the position accuracy is very high, use GPS to locate, in general, use the network location.According to the first line of code to write a positioning program, the real machine has no location information output, but the simulator has output.Finally found the problem, the mobile phone positioning mode to the mobile network positioning, rather than GP

Label:fields from the growth attribute are often configured as primary keys in MySQL, especially with the InnoDB storage engine. Because of the characteristics of the clustered index of InnoDB, fields that use the self-growing attribute are better when the primary key is performing, but using a self-increment primary key can also pose some problems. For example, using the self-increment primary key to make a database sub-table, there may be some problems such as primary key duplication, or when

Top A bug in WIN2012R2 software crash issues and patches that may arise after a cluster is installedAs the title, I read the data found that Microsoft claims to install the failure to the role of the above described problems may occur, but not only the SSMs crash.
