第一次写文章,当是记录自己的学习足迹

 学java快一年了,以此来记录下自己的学习足迹

使用软件: IDEA

于是写了个随机单词生成器

package StringDemo;
import java.util.*;
//随即单词生成器
public class RandomWordGenerator {
    private static Random rand = new Random(); //定义随机类
    private static String lowAlpha = "abcdefghijklmnopqrstuvwxyz"; //大写字母
    private static String upAlpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; //小写字母
    private static String vowel = "aiueo"; //元音
    private static String ALL = lowAlpha + upAlpha + vowel;//组合
    private static final int DEFAULT_WORD_LENGTH = 10; //默认单词长度


   //两个静态方法
    
    public static String getRandomWord() { 
        String str = "";

        for(int i = 0; i < DEFAULT_WORD_LENGTH; ++i) {
            str += ALL.charAt(rand.nextInt(ALL.length()));
        }

        return str;
    }

    public static String getRandomWord(int len) { //指定单词长度
        String str = "";
        for(int i = 0; i < len; ++i) {
            str += ALL.charAt(rand.nextInt(ALL.length()));
        }

        return str;
    }
}

以下是测试类

package StringDemo;
import java.util.ArrayList;

public class AnotherTest {
    public static void main(String[] args) {
        ArrayList randomWordList = new ArrayList();

        //随即添加10个指定长度为15的单词
        for(int i=0;i<10;++i) {
            String word = RandomWordGenerator.getRandomWord(15);
            randomWordList.add(word);
        }

        //增强for遍历
        for(String word: randomWordList) {
            System.out.println(word);
        }
    }
}

最后是测试结果:
