提供一个随机生成500个不重复部门名称的java代码

以下是一个生成500个不重复部门名称的Java代码示例：

import java.util.HashSet;
import java.util.Random;
import java.util.Set;

public class DepartmentNameGenerator {
    private static final String[] WORDS = {"Finance", "Marketing", "Sales", "Human Resources", "Information Technology", "Operations", "Customer Service", "Research and Development", "Public Relations", "Legal"};
    private static final int NUM_DEPARTMENTS = 500;

    public static void main(String[] args) {
        Set<String> departmentNames = new HashSet<>();
        Random random = new Random();
        while (departmentNames.size() < NUM_DEPARTMENTS) {
            int index1 = random.nextInt(WORDS.length);
            int index2 = random.nextInt(WORDS.length);
            String departmentName = WORDS[index1] + " " + WORDS[index2];
            departmentNames.add(departmentName);
        }
        for (String departmentName : departmentNames) {
            System.out.println(departmentName);
        }
    }
}

该代码使用了一个字符串数组来存储可能的部门名称，然后使用一个Set来存储已经生成的部门名称，确保没有重复。在while循环中，每次生成两个随机的索引，然后将对应的字符串拼接起来作为一个新的部门名称。当Set中元素数量达到指定的数量时，循环结束，最后遍历Set并输出所有的部门名称。
