Yet you have to know that whatever value you will initialize num with, this value is just a copy that exists in your object but not other objects and not the class itself<br \/>\nfor example you can make the following two objects from class X in class Y<\/p>\n<pre><code>X object_1 = new X(5);\nX object_2 = new X(12);\n<\/code><\/pre>\n<p>this doesn&#8217;t mean that you change the value of num field in class X but rather means that you made two objects that are a copy of that class and each copy has a different value of num.<br \/>\nSo the reason why you can make an object without initializing any fields, is if you for example want to access the class methods only or maybe you want the default values for the fields. btw you can overload constructors, which means you can multiple constructors that one for example that requires no arguments, so you can use this one when you want to instantiate an object without any parameters, an one that accepts an integer and you use this one when you want to initialize the value of num field when you instantiate the object example<\/p>\n<pre><code>public X () {\n\n}\n<\/code><\/pre>\n<p>and the other is <\/p>\n<pre><code>public X(int num) {\nthis.num = num\n}\n<\/code><\/pre>\n<p>Then in class Y you can make this<\/p>\n<pre><code>X object_1 = new X();\nX object_2 = new X(15);\n<\/code><\/pre>\n<p>I hope i gave you a good explanation<\/p>\n<\/p><\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p>            <span class=\"d-none\" itemprop=\"commentCount\"><\/span> <\/p><\/div>\n<\/div>\n<p>[ad_2]<\/p>\n<p>solved New object initialization in C# <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad_1] yes you can initialize an object without any parameters, let me explain simply, an object is just a copy from a class, it has a copy of all the public methods and fields inside this class.
