该怎么做这个呀，求解答

创建两个mypoint 类的对象，坐标为（3,4）和（8.9），并通过对象求这两点之间的距离。

参考一下这个帖子https://blog.csdn.net/weixin_33406440/article/details/114041057?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522166547761416800186529220%2522%252C%2522scm%2522%253A%252220140713.130102334.pc%255Fall.%2522%257D&request_id=166547761416800186529220&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~all~first_rank_ecpm_v1~pc_rank_34-1-114041057-null-null.142^v52^pc_rank_34_queryrelevant25,201^v3^control_1&utm_term=%E6%B1%82%E4%B8%A4%E4%B8%AA%E5%9D%90%E6%A0%87%E7%82%B9%E8%B7%9D%E7%A6%BBjava&spm=1018.2226.3001.4449

伪代码，自行转成 java

function distance(p1, p2) {
  x = p1.x - p2.x
  y = p1.y - p2.y
  sx = x * x 
  sy = y * y
  d = (sx+sy)^(0.5)
  return d
}
