Random strings are sequences of characters that are generated without any specific pattern or order. They are commonly used in various applications and programming languages for purposes such as generating random passwords, unique identifiers, session tokens, or test data.
Random strings are typically generated using random number generators and a set of characters. The length of the string can be determined based on the requirements of the specific use case.
Random strings can be useful in applications that require unique identifiers or random data. However, it’s important to note that the randomness of generated strings depends on the quality of the random number generator used.
In Salesforce Apex, you can generate a random string using the following code:
private static String generateRandomString(Integer len) {
final String chars = 'xaxPmno2IDdEwLzbtEvhv6oG1RDT6xQJX3MvF4amaDQ9TUvHgJfdbodlllPTnnuw';
String randStr = '';
while (randStr.length() < len) {
Integer idx = Math.mod(Math.abs(Crypto.getRandomInteger()), chars.length());
randStr += chars.substring(idx, idx+1);
}
return randStr;
}
You can call this function by passing in the desired length of the string, like this:
String randomString = generateRandomString(10);
