如何在Java Mad Libs程序中使用随机程序？

我试图做Mad Libs，但我很难试图弄清楚如何让随机数发生器从我创建的数组中选择一个随机动词，名词或形容词，因为它们都是单词，而不是数字...对于字符串句子也是一样。如何在Java Mad Libs程序中使用随机程序？

import java.util.Scanner; 
import java.util.Random; 


public class Client { 
    public static void main(String [] args){ 
     Scanner input = new Scanner(System.in); 
     Random r = new Random(); 

     //user will enter 5 nouns 
     System.out.println("Enter 5 nouns"); 
     String[] nouns = { "noun", "noun", "noun", "noun", 
      "noun"}; 
     for (int ncount = 0; ncount < 5; ncount++) { 
      System.out.print(nouns[ncount] + ": "); 
      nouns[ncount] = input.nextLine(); 
     } 



     //user will enter 5 verbs 
     System.out.println("Enter 5 verbs"); 
     String[] verbs = { "verb", "verb", "verb", "verb", 
      "noun"}; 
     for (int vcount = 0; vcount < 5; vcount++) { 
      System.out.print(verbs[vcount] + ": "); 
      verbs[vcount] = input.nextLine(); 
     } 


     //users will enter 5 adjectives 
     System.out.println("Enter 5 adjectives"); 
     String[] adjectives = { "adjective", "adjective", "adjective", "adjective", 
      "adjective"}; 
     for (int acount = 0; acount < 5; acount++) { 
      System.out.print(adjectives[acount] + ": "); 
      adjectives[acount] = input.nextLine(); 
     } 





     String sentence1 = "Longwood" + r.verbs.length + "the" + r.adjectives.length + r.nouns.length; 
     String sentence2 = "The" + noun + "in cafe3" + verb + adjective; 
     String sentence3 = "The girls will" + verb + adjective + "dresses to the" + noun; 
     String sentence4 = "Students will" + verb + adjective + "at the" + noun; 
     String sentence5 = "Students get"+ adjective + "when their" + noun + "are" + "by the staff."; 
     String sentence6 = "Recieving a day of" + noun+ verb + "me" + adjective; 
     String sentence7 = "At freshman orientation students" + verb + "about the" + adjective + noun + "on" 
     + "the roof"; 
     String sentence8 = "Senior" + noun + "is the place where you can" + verb + adjective +"!"; 
     String sentence9 = "The Longwood Varsity"+ noun + "team" + verb + "Long Island" + adjective + "For 2015!"; 
     String sentence10 = "The teacher of my" + noun + "class" + verb + adjective;

使用数组和随机化索引。 –

谢谢！我会尝试的！ :) – Littlesims2chick

我使用数组虽然...：S – Littlesims2chick

您可以通过执行

String[] array = new String[x]; //x is the size of the array

要选择一个随机单词做没有任何价值空白的阵列，可以使用随机的nextInt用绑定的数组的大小。您得到的随机数将是要使用的单词的索引
