然后,使用`RandomStringUtils`类的`randomAlphanumeric()`方法生成随机字符串。 示例代码如下: ```java import org.apache.commons.lang3.RandomStringUtils; public class RandomStringGenerator { public static String generateRandomString(int length) { return RandomStringUtils.randomAlphanumeric(length); } ``` ...
public class CommonsLangRandomStringGenerator { public static String generateRandomString(int length) { // 使用RandomStringUtils生成随机字符串 return RandomStringUtils.randomAlphanumeric(length); } } 调用方法并打印生成的随机字符串: java public static void main(String[] args) { String randomString ...
可以使用RandomStringUtils类来生成随机字符串。以下是一个示例代码: importorg.apache.commons.lang3.RandomStringUtils;publicclassRandomStringGenerator{publicstaticStringgenerateRandomString(intlength){returnRandomStringUtils.randomAlphanumeric(length);}publicstaticvoidmain(String[]args){intlength=10;StringrandomString...
* Create an alphanumeric string generator. */ public RandomString(int length, Random random) { this(length, random, alphanum); } /** * Create an alphanumeric strings from a secure generator. */ public RandomString(int length) { this(length, new SecureRandom()); } /** * Create session...
1、Java使用RandomStringUtils类 它的方法可以生成只包含字母(随机字母)、数字(随机数字)或两者(随机字母数字)的随机字符串 importorg.apache.commons.lang.RandomStringUtils;publicclassRandomStringGenerator {publicstaticvoidmain(String[] args) {//generate a random string of 10 alphabetsString randomString = Rand...
sb.append(String.valueOf(newRandom().nextInt(10)));break; } }returnsb.toString(); } 3、org.apache.commons.lang包下有一个RandomStringUtils类,其中有一个randomAlphanumeric(int length)函数,可以随机生成一个长度为length的字符串。 Stringfilename=RandomStringUtils.randomAlphanumeric(10); ...
}publicstaticString reverse5(String orig) {char[] s =orig.toCharArray();intn = s.length - 1;inthalfLength = n / 2;for(inti = 0; i <= halfLength; i++) {chartemp =s[i]; s[i]= s[n -i]; s[n- i] =temp; }returnnewString(s); ...
Java 获取随机数的方法有哪些？1.使用org.apache.commons.lang.RandomStringUtils.randomAlphanumeric(10)...
public static void main(String[] args) { RandomAlphaNumericGenerator randomTest = new RandomAlphaNumericGenerator(11); for(int i=0;i<10;i++){ String result = null; do { result = randomTest.nextString(); } while (!result.matches(".*(?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=...
RandomPasswordGenerator passGen = new RandomPasswordGenerator(); String password = passGen.generatePassayPassword(); int specialCharCount = 0; for (char c : password.toCharArray()) { if (c >= 33 || c <= 47) { specialCharCount++;
