java中break和continue跳出指定循环

loop1:for(int x = 0; x < 4; x++)
        {
            loop2:for (int y = 0; y < 5 ; y++ )
            {
                System.out.println("x="+x+",y="+y);
                if (y==2)
                {
                    break loop1;
                }
            }
        }

loop1:for(int x = 0; x < 4; x++)
        {
            loop2:for (int y = 0; y < 5 ; y++ )
            {    if (x==2)
                {
                    continue loop1;
                }
                System.out.println("x="+x+",y="+y);
            }
        }
