如何按顺序命名新实例？ [英] How do i name new instances in order?

问题描述

你好，

我是OOP的新手。我不得不从C＃创建结构，但在Java中它不存在所以我创建了类。这个班叫做人。并且在类字符串和浮点类型中有关于人（小孩）的一些信息。在我的程序中，有时我需要生成新人。我猜这叫做创建新实例，对不起，如果我错了。因为我需要以后为特定人使用信息。所以我想我可以将他们命名为person01，person02或者他们的名字。但我不能这样做。有办法吗？或者有解决方法吗？也许有一种简单的方法可以做到我不知道。





BTW

Hello,
I am new to OOP. I had to create "structs" from C# but in Java it doesn't exist so i created class. This class is called person. And there are some info about person(child) in class string, and float types. In my program sometimes i need to generate new person. I guess that's called creating new instance, sorry if i am wrong. Because I need to use infos for spesific person later. So i thought i could name them person01,person02 or by their names. But i can't do it. Is there a way to do it? Or is there any solution way for this? Maybe there is easy different way to do it that i do not know.


BTW

public class child {
	public static String name;
	public static float foodConsumed;
	public static float sleepConsumed;
	public static float gameConsumed;
	public static float hygieneConsumed;
	
	public static void add(){
		Random rnd = new Random();
		child.name="child"+num;
		child.foodConsumed= (float) ((rnd.nextInt(150)+50)*0.01);
		child.gameConsumed= (float) ((rnd.nextInt(150)+50)*0.01);
		child.sleepConsumed= (float) ((rnd.nextInt(75)+25)*0.01);
		child.hygieneConsumed= (float) ((rnd.nextInt(50)+20)*0.01);
		Main.num++;
		Main.childQnt++;
	}
}

这个孩子我必须稍后生成..



我尝试了什么：



我试图使用变量，如child01，child02：

子变量=新子（）;



但这不太有效。

This childs i have to generate later..

What I have tried:

I tried to use variable which changes like child01,child02:
child variable = new child();

But this didn't quite work.

推荐答案

否且它将永远不会起作用，因为您已将所有属性设置为静态，因此它们适用于子的每个实例。从所有这些属性中删除static关键字，然后您可以创建任意数量的对象，例如：

No and it will never work because you have made all the properties static, so they apply to every instance of child. Remove the static keyword from all those properties, and then you can create any number of objects like:

child Robert = new child();
Robert.name = "Robert";
// ...
child Mary = new child();
Mary.name = "Mary";
// etc
