java generate random string

Generate a number of 6 ~ 16 user names, mainly text operations, the colleague premise is to have a string package. consists of three programs. Program one: Responsible for the random extraction of data from the dictionary, write a new file. (1.php) * * Extract the random value from the dictionary file. $file 1 = "./wor

Pull Bastard: Many people have received a variety of invitation code, but few people to study the invitation code is if generated, in the project encountered generate random six-bit invitation code, and the invitation code in the database store, so that is the invitation code can not be repeated. Idea: I used to generate four invitation codes for example. We can

Wrote a program, mainly used to detect the MySQL database empty password and weak password,Here, three types of weak passwords are defined:1. Continuous numbers, such as 123456, are implemented in Get_weak_num2. Continuous letters, such as ABCDEF, are implemented in Get_weak_characterOf course, the numbers are random.3. Random combination of numbers and letters. Implemented in Get_weak_num_character.A list

has been used to generate the verification code method, take 4 digits no problem, the result plus the letter, take 6 digits, the efficiency is very low. Improved a bit, the method is as follows Copy Code code as follows: var text2 = ""; var random = new Random ((int) DateTime.Now.Ticks); Const string Text

This article describes how to use PHP to generate a function with a random string with a custom length. For more information, see Php randomly generated strings can be customized to define their own length, which is often encountered in practical application development. The Code is as follows: // Randomly generate

Unique Code Random Code The more specific needs are this The database may gradually insert no more than 10w records, want to add a field, each record of the value of this field is a 8-bit code 1. It looks like a random code, like Dlkpownd Ouichgeb. 2. Can not be "easy" to crack such as id=1 corresponding to the aaaaaaaa id=2 corresponding Aaaaaaab of course, this description may be repeated with the fir

only reference a small amount of information, with an average of 0.2 articles referenced in one paper. Reference information can be randomly added as mentioned in a paper on the experiment dataset using dblp. Inspired by this, I intend to add 20 random references to each paper, so I wrote the following SQL statement: String SQL = "insert into citation (pId1, pId2) values (select pId from papers limit ?, 1)
