java - 数组无法正确显示

Question

当我运行该程序时，它打印出索引中的数字，而不是打印出单词。该程序的想法是创建随机句子，有人知道我在这里做错了什么吗？

 public class TestShoutBox5 {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here
      String Subjects[] = new String[]{"My Teacher","I","You"
   };

   Random RandomSubject=new Random();
   int S = RandomSubject.nextInt(4);

     String Objects[] = new String[]{"Homework", "Work","Quiz"
   };

   Random Randomobjects=new Random();
   int O = Randomobjects.nextInt(4);

 String Verbs[] = new String[]{"Studying", "Playing","Working"
   };

   Random Randomverbs=new Random();
   int R = Randomverbs.nextInt(4);

    String Adjectives[] = new String[]{"Smart", "Tall","Hard"
   };

   Random RandomAdjectives=new Random();
   int A = RandomAdjectives.nextInt(4);

    String Adverbs[] = new String[]{"quickly", "everywhere","fast"
   };

   Random RandomAdverb=new Random();
   int Ad = RandomAdverb.nextInt(4);



 System.out.print("Your Sentence"+S+O+R+A+Ad);

}

}

Answer 1

问题是您正在打印索引而不是数组中软管索引处的单词。而不是:

System.out.print("Your Sentence"+S+O+R+A+Ad);

这样做:

System.out.print("Your Sentence"+ Subjects[S]+Objects[O]+Verbs[R]+Adjectives[A]+Adverbs[Ad]);

编辑(来自@kyriacos_k的评论):

当数组索引从 0 到数组长度 - 1 时，Random 对象应该创建 0 - 2 之间的值，而不是 0 - 3 之间的值。要解决此问题，请使用 .nextInt(3) 而不是 .nextInt(4)
