Question

java里升序和降序最简短的代码分别是什么？

Answer 1

直接调用jdk里面的方法Arrays.sort(args)方法。而且这个方法重载实现了多个参数，排序下标[N~M]位数字~倒叙，升序等等~

for (int i = 0; i < list.size(); i++) {

for (int j = i + 1; j < list.size(); j++) {

if (list.get(i) > list.get(j)) {

int temp = list.get(i);

list.set(i, list.get(j));

list.set(j, temp);

}

}

}

System.out.println("升序：" + list);

for (int i = 0; i < list.size(); i++) {

for (int j = i + 1; j < list.size(); j++) {

if (list.get(i) < list.get(j)) {

int temp = list.get(i);

list.set(i, list.get(j));

list.set(j, temp);

}

}

}

System.out.println("降序：" + list);
