编写一个程序，对数组a[]={20,10,50,40,30,70,60,80,90,100}进行从大到小排序，并打印排序后的结果

Answer 1

public class C {

public static void main(String[] args) {
int[] ary = {20,10,50,40,30,70,60,80,90,100};

sort(ary);
System.out.println("After sort, array item is: ");
for(int i = 0; i < ary.length; i++){
System.out.print(ary[i] + " ");
}

}

private static void sort(int[] ary) {

for(int i = 0; i < ary.length - 1; i++){

for(int j = i + 1; j < ary.length; j++){
if(ary[j] > ary[i]){
int temp = ary[i];
ary[i] = ary[j];
ary[j] = temp;
}
}

}
}

}

------------------testing
After sort, array item is:
100 90 80 70 60 50 40 30 20 10
