The code below show you how to use the Apache Commons-Lang RandomStringUtils
class to generate some random string data.
package org.kodejava.example.commons.lang;
import org.apache.commons.lang3.RandomStringUtils;
public class RandomStringUtilsDemo {
public static void main(String[] args) {
// Creates a 64 chars length random string of number.
String result = RandomStringUtils.random(64, false, true);
System.out.println("random = " + result);
// Creates a 64 chars length of random alphabetic string.
result = RandomStringUtils.randomAlphabetic(64);
System.out.println("random = " + result);
// Creates a 32 chars length of random ascii string.
result = RandomStringUtils.randomAscii(32);
System.out.println("random = " + result);
// Creates a 32 chars length of string from the defined array of
// characters including numeric and alphabetic characters.
result = RandomStringUtils.random(32, 0, 20, true, true, "qw32rfHIJk9iQ8Ud7h0X".toCharArray());
System.out.println("random = " + result);
}
}
The example of our program result are:
random = 2807246146525875794860509906530938229981588250176397328237925194
random = SWMZqKHTfWkJOIMMliShJKSGHIiBcQJxukwLQxazxZymuSCyLVCDTYsFehrIPwRr
random = e}&"_8Ek%F'7&_T8\G~YPEG2#N-^_|xw
random = 0IHI8dIk2Xf0fJX0HqJr78dq7w92Qd0U
