求JAVA code: 26个字母里随机出现10个字母,其中至少含有两个元音字母(元音字母:a,e, i,o,u)

不知道你这10个字母中是否能出现重复的字母！ import java.util.Random;import java.util.ArrayList;public class RandomChar{ public char[] Vowel = {'a', 'e', 'i', 'o', 'u'};public String[] Consonant = {"b","c","d","f","g","h","j","k","l","m","n","p","q","r","s","t","v","w","x","y","z"};public ArrayList Rusult = new ArrayList();public RandomChar() { } public void getChar() { ArrayList VowelAL = new ArrayList();ArrayList ConsonantAL = new ArrayList();//VowelAL = genarate(Vowel[]);//ConsonantAL = genarate(Consonant[]);//下面两个for循环主要输初始化arrayList for(int i = 0;i <21;i++ ) { ConsonantAL.add( Consonant[i] );} for(int j = 0;j <5;j++ ) { VowelAL.add( Vowel[j] );} int randNum01;int randNum02;int randNum03;int randNum04;int rangeNum01 = 21;int rangeNum02 = 5;int ConsonantNum = 8;int VowelNum = 2;//这个是代表输出8个辅音的同时输出元音的个数 for(int i = 0;i<ConsonantNum;i++) { Random ran = new Random(System.currentTimeMillis()+i);randNum01 = ran.nextInt(rangeNum01);randNum02 = ran.nextInt(2);//randNum02主要是来控制是否输出元音， //这个数也是随机的因此在结果集中的位置就是随机的了 if(randNum02 == 1 &&VowelNum !=0) { randNum03 = ran.nextInt(rangeNum02);System.out.print(VowelAL.get(randNum03));Rusult.add(VowelAL.get(randNum03));VowelAL.remove(randNum03);//通过remove语句将输出过的字符删除 VowelNum = VowelNum - 1;//元音已输出个数减一 rangeNum02 = rangeNum02 - 1;//同样随机数的范围减一 } System.out.print(ConsonantAL.get(randNum01));Rusult.add(ConsonantAL.get(randNum01));ConsonantAL.remove(randNum01);//通过remove语句将输出过的字符删除 rangeNum01 = rangeNum01 -1;//同样随机数的范围减一 } //判断是否已经输出2个字符，没有则在后面补充输入；这样的情况同样是随机的 if (VowelNum != 0) { for (int k = 0;k <VowelNum;k++) { Random ran = new Random(System.currentTimeMillis());randNum04 = ran.nextInt(rangeNum02);System.out.print(VowelAL.get(randNum04));Rusult.add(VowelAL.get(randNum04));VowelAL.remove(randNum04);rangeNum02 = rangeNum02 -1;} } } public void PrintRes() { for(int i = 0;i <10 ;i++) { System.out.println(Rusult.get(i));} } public static void main(String str[]) { RandomChar rand = new RandomChar();System.out.print("下面是getChar函数中的print输出的字符：");rand.getChar();System.out.println();System.out.println("下面是PrintRes函数中通过存储的Arraylist输出的字符：");rand.PrintRes();}} 收起
