帮助降序浮动。我试图按降序排序小数＃。当我运行该程序时，它不会解决它。任何人都可以帮我吗？

Help with Decending order for float. I am trying to sort out decimal #'s in Decending order. When i go run the program it dosen't sort it out. Can anyone help me out?

import java.util.Arrays;

public class SelectionSort {

	public static void main(String[] args) {
	
	// initialize a new float array
	float[] a = new float[]{1.12f,7.32f,3.21f,1.07f,9.2f,1.7f,10.12f};
	
	
	java.util.Collections.reverseOrder();
	
	// print the sorted array of float
	System.out.println(Arrays.toString(a));

	}
}

What I have tried:

I tried Array.sort. now im trying java.util.

推荐答案

也许如果你传递了想要对该函数进行排序的数组，它会有所帮助： br />

Perhaps if you passed the array you wanted to sort to the function, it would help:

java.util.Collections.reverseOrder();

它不是猜猜你想要排序的东西！
