RandomTools Tutorial

The RandomTools class provides methods for generating random integers and strings. These methods can be used when you need random values for testing, simulations, or other purposes.

Methods

1. generateRandomNumber(int numDigits)

Generates a random integer with the specified number of digits.

• Parameters:
  • numDigits: The number of digits for the random number.
• Returns: A random integer with the specified number of digits.

Example:

int randomNumber = RandomTools.generateRandomNumber(6);
// randomNumber will be a 6-digit random number

2. generateRandomNumber()

Generates a random integer with 6 digits.

• Returns: A random 6-digit integer.

Example:

int randomNumber = RandomTools.generateRandomNumber();
// randomNumber will be a 6-digit random number

3. generateRandomString(int length)

Generates a random string with the specified length.

• Parameters:
  • length: The length of the random string.
• Returns: A random string with the specified length.

Example:

String randomString = RandomTools.generateRandomString(6);
// randomString will be a 6-character random string

4. generateRandomString()

Generates a random string with 6 characters.

• Returns: A random 6-character string.

Example:

String randomString = RandomTools.generateRandomString();
// randomString will be a 6-character random string
