关于java中labeled break(goto)用法疑问

书上说：a block being labeled can be a stand-alone block, or a statement that has a block as its target.大概翻译过来是：使用break时，标记的块可以是一个独立的块，或者是一个指向块的语句。请问什么叫做指向块的语句呢？哪位大侠可以给个实例么？非常感谢！
附带一个labeled break使用实例：import java.util.*;public class LabeledBlock
{
    public static void main(String[] args)
    {
        int i;
        for (i = 1; i < 4; i++)
        {
            one:
            {
                two:
                {
                    three:
                    {
                        System.out.println("\ni is " + i);
                        if (i == 1)
                        break one;
                        if (i == 2)
                        break two;
                        if (i == 3)
                        break three;
                        System.out.println("won't print");
                    }
                    System.out.println("After block three.");
                }
                System.out.println("After block two.");
            }
            System.out.println("After block one.");
        }
        System.out.println("After for.");
    }
}
