随机生成五位数并排序

package Array;
import java.util.Arrays;
import java.util.Random;
public class ScPx {
public static void main(String args[]){
Random ran = new Random();
int[] a = new int [5];
for(int i=0;i<5;i++){
a[i] = ran.nextInt(10);
}
for(int i=0;i<4;i++){
for(int j=i+1;j<5;j++){
if(a[i]<a[j]){
int r=a[i];
a[i]=a[j];
a[j]=r;
}
}
}
System.out.println(Arrays.toString(a));
}
}
