To get the last element of a ArrayList in Java, we can use themethod by passing its indexlist.size()-1. Here is an example, that returns the last element40from the following ArrayList: importjava.util.Arrays;importjava.util.List;publicclassMain{publicstaticvoidmain(String[]args){List<Integ...
Here is a code example to get both the first and last elements from ArrayList in Java. It's pretty straightforward, all you need to do is call get(0) to get the first element and callget(size() - 1)to retrieve the last element. In this example, we have an ArrayList of video game...
To get the last value of an ArrayList in Java, you can use the size() method to get the size of the list and then access the value at the index size() - 1.
System.out.println(linkedList.element()); System.out.println(linkedList.contains("A")); System.out.println(linkedList.element()); System.out.println(linkedList.get(4)); System.out.println(linkedList.getFirst()); System.out.println(linkedList.getLast()); System.out.println(linkedList.indexOf("...
可以看到 ArrayList 的 get 方法只是通过数组下标从数组里面拿一个元素而已,所以 get 方法的时间复杂度是 O(1) 常数,和数组的大小没有关系,只要给定数组的位置就能定位到数据,而 Java 中 ArrayList 是基于数组实现的,数组是内存地址连续的空间,取值其实是地址的偏移,所以自然块的多。
println("索引值为 2 的元素为: " + element); } }执行以上程序输出结果为:Numbers ArrayList: [22, 13, 35] 索引值为 2 的元素为: 35以上实例中,使用 get() 方法用于访问索引值为 2 的元素。注意:我们还可以使用 indexOf() 方法返回 ArrayList 中元素的索引值。要了解更多信息,请访问 Java ArrayList...
