javaarraylist数组排序

要对Java ArrayList进行排序，可以使用Collections类中的sort方法。调用`Collections.sort(list)`方法可以实现升序排序。下面是一个示例代码：

import java.util.ArrayList;
import java.util.Collections;

public class ArrayListTest {
   public static void main(String[] args) {
      ArrayList<Integer> list = new ArrayList<Integer>();
      list.add(60);
      list.add(20);
      list.add(99);
      list.add(10);
      Collections.sort(list); //排序
      System.out.println(list);
   }
}

这段代码将输出排序后的ArrayList: [10, 20, 60, 99。。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
