In Java, arguments are passed to methods by value. This means that when you pass an argument to a method, the method receives a copy of the argument rather than a reference to the original object. For example, consider the following code: public class Main { public static void main(...
Pass-by-reference: A reference (memory address) to the original variable is passed to the method. Changes within the method modify the original variable.Key Points:Java always passes a copy of the value (primitive value or object reference). For primitives, the copy is independent, so changes...
Is Java pass by reference or pass by value?Brian L. Gorman
Pass by reference: An alias or reference to the actual parameter is passed to the method. The method accesses the actual parameter. Often, the confusion around these terms is a result of the concept of theobject referencein Java. Technically, Java is always pass by value, because even though...

首先我们必须知道的是,java里面一切皆对象,类本身也是会当成对象来处理,主要体现在类的.class文件,其实加载到java虚拟机之后,也是一个对象,它就是Class对象,全限定类名:java.lang.Class。 那这个isAssignableFrom()其实就是Class对象的一个方法: /** * Determines if the class or interface represented by this ...
