java - 极值 - 排序 - 比较 (Arrays.toString() 和 Sort())

import java.util.Arrays;

public class SortTest {
    public static void main(String[] args) {
        double n1 = Float.MIN_VALUE;
        double n2 = Integer.MIN_VALUE;
        double n3 = Integer.MAX_VALUE;
        double n4 = -Integer.MAX_VALUE;
        double n5 = -Short.MIN_VALUE;
        double n6 = 2000000000;
        double n7 = 7.8e9;
        double n8 = Double.MIN_VALUE;

        double[] dd = {n1, n2, n3, n4, n5, n6, n7, n8};

        System.out.println(Arrays.toString(dd));
        Arrays.sort(dd);
        System.out.println(Arrays.toString(dd));

    }
}
