在main中调用一个方法从其他类填充数组 - 返回相反的位置

Question

我需要编写一个方法FillPinDouble，它将使用Math.sqrt（）填充一个名为doublepin的数组，其值为√n，√n-1，√n-2，..，√1。 / p>

在我的main方法中，我应该调用此方法来填充doublepin arr。我应该打印一次数组，然后再反复打印。例如，如果我的数组是[2,8,16,9]那么它应该打印为[9,16,8,2]。这就是我到目前为止所做的：

public static double FillPinDouble()
{
double n;
double[] doublepin=new double[n];
for(i=0;i<n;i++) // i wonder about ... on the √n,√n-1,√n-2,..,√1 how much would it be.The number 6 i chose it 5 slots are for sure in the array.= but may need more
  {
    double m=(double) (Math.random() * 101) // i try to use math random for 
    creating √n,√n-1,√n-2,..,√1 .I cant figure out how can i be this
     doublepin[1]=√n
     doublepin[2]=√n-1
     doublepin[3]=√n-2
     doublepin[4]=√1 // may needs and other slots double[5],[6],[7],..
   }
System.out.println([i]);
return doublepin[i]; // return the double array
}//end method

在我的主要方法中，我会这样称呼：

 double x; // i did this to save the method(the array)
    x=Klashkalw.FillPinDouble(); // i call the method and i save it to x.
    System.out.println(x); //i dont know after how i  change from last to the beggining i may have mistakes because i try to do something is unknowledge for me.
