The Set Value of the list, which is related to the location of the variable (the result varies greatly due to the change of the variable range)

The result we want is:

[Regntypecharge: NULL, null, 1, null,]
[Regntypecharge: NULL, null, hehe, null,]

The required code is:

Package com. kompakar. eHealth. server. regn. mstr. Common. Service. impl;

Import java. util. arraylist;
Import java. util. List;

Import com. kompakar. eHealth. model. Bridge. Bo. regntypecharge;
Import com. kompakar. eHealth. model. regn. mstr. Common. View. regntypechargeview;

Public class test {

/**
* @ Param ARGs
*/
Public static void main (string [] ARGs ){

Regntypecharge BO = new regntypecharge ();
Bo. setvisittype ("1 ");
Regntypecharge bo2 = new regntypecharge ();
Bo2.setvisittype ("hehe ");

List <regntypecharge> List = new arraylist <regntypecharge> ();
List. Add (BO );
List. Add (bo2 );


List <regntypechargeview> list2 = new arraylist <regntypechargeview> ();

// Regntypechargeview view = new regntypechargeview ();
For (INT I = 0; I <list. Size (); I ++ ){
Regntypechargeview view = new regntypechargeview ();
View. setregntypecharge (list. Get (I ));
List2.add (View );

}

System. Out. println (list2.get (0). getregntypecharge ());
System. Out. println (list2.get (1). getregntypecharge ());
System. Out. println (list2.get (0 ));
System. Out. println (list2.get (1 ));

}

}

 

If you write this statement:

Package com. kompakar. eHealth. server. regn. mstr. Common. Service. impl;

Import java. util. arraylist;
Import java. util. List;

Import com. kompakar. eHealth. model. Bridge. Bo. regntypecharge;
Import com. kompakar. eHealth. model. regn. mstr. Common. View. regntypechargeview;

Public class test {

/**
* @ Param ARGs
*/
Public static void main (string [] ARGs ){

Regntypecharge BO = new regntypecharge ();
Bo. setvisittype ("1 ");
Regntypecharge bo2 = new regntypecharge ();
Bo2.setvisittype ("hehe ");

List <regntypecharge> List = new arraylist <regntypecharge> ();
List. Add (BO );
List. Add (bo2 );


List <regntypechargeview> list2 = new arraylist <regntypechargeview> ();

Regntypechargeview view = new regntypechargeview ();
For (INT I = 0; I <list. Size (); I ++ ){
// Regntypechargeview view = new regntypechargeview ();
View. setregntypecharge (list. Get (I ));
List2.add (View );

}

System. Out. println (list2.get (0). getregntypecharge ());
System. Out. println (list2.get (1). getregntypecharge ());
System. Out. println (list2.get (0 ));
System. Out. println (list2.get (1 ));

}

}

This will result in

[Regntypecharge: NULL, null, hehe, null,]
[Regntypecharge: NULL, null, hehe, null,]
