ListArray listArray = new ListArray(); listArray.add("a"); listArray.add("b"); //没有重写toString()方法,只能调用原始的Object方法输出地址 listArray.add(0,"c"); listArray.remove(0); System.out.println(listArray); } } /** * 用数组实现ArrayList * 泛型不写,固定为String */ class L...
In this tutorial, we will learn about how to create an ArrayList from an Array in Java. ArrayList belongs to java.util package.
Once the array of objects is instantiated, you have to initialize it with values. As the array of objects is different from an array of primitive types, you cannot initialize the array in the way you do with primitive types. In the case of an array of objects, each element of array i....
概述ArrayList 是 List 接口下一个基于可扩展数组的实现类,它和它的兄弟类 Vector 有着一样的继承关系,也都能随机访问,但是不同的是不能保证线程安全。 这是关于 java 集合类源码的第三篇文章。往期文章: java集合源码分析(一):Collection 与 AbstractC
