[code="java"]
StringBuilder sb=new StringBuilder("*********");
for(int i=0;i<5;i++){
System.out.println(sb);
int n=sb.length()-1;
sb.deleteCharAt(n);
sb.deleteCharAt(n-1);
sb.insert(0,' ');
}
[/code]

虽然有那么点无聊，但是也算一种解法，你不让再循环这个星号还真不好打出来
[code="java"]
public static final String[] array={"*********"," *******"," *****"," ***"," *"};

public static void main(String []args){
for(int i=0;i<array.length;i++){
System.out.println(array[i]);
}
}

[/code]
