it delegates it to the parent classloader. This is how uniqueness is maintained in the runtime environment. If the parent class loader doesn’t find the class then the class loader itself tries to load the class. Let’s understand this by executing the below java program...
Every Java Virtual Machine (JVM) is equipped with a built-in class loader known as the primordial class loader. This specific class loader holds a unique status within the virtual machine. It is considered special because the JVM assumes that the primordial class loader has access to a reposito...
