JDK5.0 break 标签的用法

 public class MyTest {
 public static void main (String[] args){
  Random random = new Random(48);
  outer1:
  for(int i=0; i<100; i++){
   int j = random.nextInt(26)+'a';
   System.out.print((char)j + ","  + i + ";" );
   outer2:
   switch(j){
    case 'a':
    case 'e':
    case 'i':
    case 'o':
    case 'u': System.out.println("vowel");
      break outer2;
    case 'y':
    case 'w': System.out.println("sometimes a

 

vowel");
      break outer1;
    default : System.out.println("consonant"); 
   }
  }
 }
}
