以下是使用 Java 生成企业统一信用代码的示例代码：```javaimport java.util.Random;public class GenerateEnterpriseCreditCode {public static void main(String[] args) {String code = generateCreditCode();System.out.println(code);}public static String generateCreditCode() {Random random = new Random();StringBuilder builder = new StringBuilder();String[] provinceCodes = {"11", "12", "13", "14", "15", "21", "22", "23", "31", "32", "33", "34", "35", "36", "37", "41", "42", "43", "44", "45", "46", "50", "51", "52", "53", "54", "61", "62", "63", "64", "65"};String provinceCode = provinceCodes[random.nextInt(provinceCodes.length)];builder.append(provinceCode);int[] weights = {1, 3, 9, 27, 19, 26, 16, 17, 20, 29, 25, 13, 8, 24, 10, 30, 28};int sum = 0;for (int i = 0; i < weights.length; i++) {int digit = random.nextInt(10);builder.append(digit);sum += digit * weights[i];}int checkCode = 31 - sum % 31;if (checkCode == 31) {checkCode = 0;}if (checkCode == 30) {builder.append("Y");} else {builder.append(checkCode);}return builder.toString();}}```该代码使用随机数生成一个随机的省份代码和15个数字，然后根据企业统一信用代码的计算规则生成校验码，并将所有部分组合成最终的统一信用代码。
