package class1;

public class Welcome {

  /**
   * @param args
   */
  public static void main(String[] args) {
    // TODO Auto-generated method stub
String[] greeting = new String[3];
greeting[0] = "AA爱学习！";
greeting[1] = "BBB爱学习！";
greeting[0] = "AA和BBB都爱学习！";

for(String s : greeting){
  System.out.println Moon

;
}
}

}

为什么显示的答案是：
AA和BBB都爱学习！
BBB爱学习！
null
