Java 实例 - 数组反转

ArrayList<String> arrayList = new ArrayList<String>();

arrayList.add("A");

arrayList.add("B");

arrayList.add("C");

arrayList.add("D");

arrayList.add("E");

System.out.println("反转前排序: " + arrayList);

Collections.reverse(arrayList);

System.out.println("反转后排序: " + arrayList);

反转前排序: [A, B, C, D, E]

反转后排序: [E, D, C, B, A]
