Java进行循环创建对象的n个量

本文介绍了Java进行循环创建对象的n个量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我需要一些帮助。我想创建一个for循环，创建一个类，对象的n个，然后将其添加到一个ArrayList。事情是这样的：

//播放器是一个自定义类ArrayList的＆LT;玩家GT; numberofPlayersArray;numberofPlayersArray =新的ArrayList＆LT;播放器及GT;（）;// n是，我想创建Player类对象的数量变量  的for（int i = 0; I＆LT; N;我++）  {    //这是我能想出但我失去了一些东西     玩家P;     P =新播放器     numberofPlayersArray.add（P）;    }

任何帮助将AP preciated

解决方案

//播放器是一个自定义类ArrayList的＆LT;玩家GT; numberofPlayersArray =新的ArrayList＆LT;播放器及GT;（N）;// n是，我想创建Player类对象的数量变量的for（int i = 0; I＆LT; N;我++）{    //这是我能想出但我失去了一些东西     玩家P =新的球员（）;     numberofPlayersArray.add（P）;}

请注意，这是更好地初始化的ArrayList 的大小，如果它是已知的（如你的情况）

I need some help. I want to create a for loop that creates n number of objects of a class, and then adds them into an arraylist. Something like this:

//Player is a custom class ArrayList<Player> numberofPlayersArray; numberofPlayersArray = new ArrayList<Player>(); //n is a variable for the number of Player class objects that I want to create for(int i = 0; i < n; i++) { //this is what I can come up with but I am missing something Player p; p = new Player numberofPlayersArray.add(p); }

Any help would be appreciated

解决方案

//Player is a custom class ArrayList<Player> numberofPlayersArray = new ArrayList<Player>(n); //n is a variable for the number of Player class objects that I want to create for(int i = 0; i < n; i++) { //this is what I can come up with but I am missing something Player p = new Player(); numberofPlayersArray.add(p); }

Note that it's better to initialize the ArrayList with the size, if it is known (as in your case)
