Big Smile

不能运行,但是居然能编译过去..怕怕...



package untitled2;

public class StrLenth {
  public static void main(String[] args) {

    String sB[] = new String[3];
    sB[0] = new String("hello");
    sB[1] = "world";
    sB[13]="坏蛋";    
    System.out.println(sB[0] + " " + sB[13]);
    
    int iC[]=new int[3];
    iC[19]=16;     
    System.out.println(iC);
    
    
  }
}
