Java数组排序，比较大小

public class AvgTest {public static void main(String[] args) {Scanner sc=new Scanner(System.in);double[] a=new double[3];for(int i=0;i<a.length;i++){System.out.println("请输入第"+(i+1)+"个数:");a[i]=Double.parseDouble(sc.next());}double max=0.0d,min=0.0d;Arrays.sort(a);max=a[a.length-1];min=a[0];System.out.println("最大值是:"+max);System.out.println("最小值是："+min);}}
