改错

import java.util.Random;
public class Test {
   private static Random rnd = new Random();
   public static void main(String[] args) {
      StringBuffer word = null;
      switch(rnd.nextInt(2)) {
          case 1:  
             word = new StringBuffer('P');
             break;
          case 2:  
             word = new StringBuffer('G');
             break;
          default:
             word = new StringBuffer('M');
             break;
      }
      word.append('a');
      word.append('i');
      word.append('n');
      System.out.println(word);
   }
}

要想等概率输出Pain,Gain,Main该怎么改?

好熟悉的代码。

多输出几次吧 用个循环多来几次 再统计一下

import java.util.Random;
public class Test {
private static Random rnd = new Random();
public static void main(String[] args) {
StringBuffer word = null;
switch(rnd.nextInt(2)) {
case 1:
word = new StringBuffer("p");
break;
case 2:
word = new StringBuffer("g");
break;
default:
word = new StringBuffer("m");
break;
}
word.append('a');
word.append('i');
word.append('n');
System.out.println(word);
}
}


It's OK!
