It maintains the insertion order of the elements. Resizable-array implementation of the List interface. Java ArrayList allows duplicate and null values. We have used the size() method to obtain the ArrayList size, then fetched its element using the get() method and assigned each element to the respected array element by using the assignment (=) operator.

You need to use boxed types like Integer, Character, Boolean etc. If a and b are two vectors, then the assignment a = b makes a into a new vector with the same length as b, and all elements are copied from b to a. Java ArrayList Java 集合框架 ArrayList 类是一个可以动态修改的数组,与普通数组的区别就是它是没有固定大小的限制,我们可以添加或删除元素。 ArrayList 继承了 AbstractList ,并实现了 List 接口。 ArrayList 类位于 java.util 包中,使用前需要引入它,语法格式如下: import java.util.ArrayList; // 引入 ArrayList … In each line there are zero or more integers.
