How to create two(or more) different classloader for loading the same class file twice or more

[Bhagirathi Mallick]

Let I have a class named as Loading..

public class Loading {
    public  int load=10;
    
    public   void afterloadingbeforeModifing(){
    
        System.out.println(" INSIDE METHOD OF  afterloadingbeforeModifing()");
     
    
        public   void afterModifing(){
    
        System.out.println("  After modified Incremented Value of load "+load);
    }
        static{
           System.out.println(" Incrementing Value of load"); 
           
        }
   

}

After some time I want to modify the content of a method afterModifing() the same class as follows

public class Loading {
    public  int load=10;
    
    public   void afterloadingbeforeModifing(){
    
        System.out.println(" INSIDE METHOD OF  afterloadingbeforeModifing()");
     
    
        public   void afterModifing(){
    
        System.out.println(" MODIFIED");
    }
        static{
           System.out.println(" Incrementing Value of load"); 
           
        }
   

}

I want that modified statement should be execute...
i think if i load the class file by another classloader then it will be reflect..

If y people have any solution please replay...
Thanks in advance...

Bhagirathi,

1. I've edited your subject line to remove the all-caps. Please read the EaseUp (←click) page on this subject.

2. Could you please re-state your question? I still have no idea what you want, or why you would want to load multiple versions of the same class. A bit of background would be useful. (ie, TellTheDetails (←click)).

So if I understand your actual problem description, you have a class which behaves one way, and then after a while (I assume this has a precise definition) you want it to behave differently.

If that's the case, then having two versions of the class and having them both loaded by separate classloaders is, well, um, let me just say, it isn't the most obvious or straightforward way to achieve that. I would achieve that by providing the class with a flag which controls the decisions to work the "early" way and the "late" way, and then just set the flag when you want to switch over.
