smartcard - Using javacard Shareable class to share an interface between two applet as client and server with different package? -

-

i want share interface between 2 applets client , server different package aid. saw link: [0x6f00 error casting javacard shareable interface

in above link said: both client , server have in same package. have question now. possible client uses server functions if have different package aid? thank much.

client , server don't have in same package! both need depend on same package, contains shared interface.

in linked question, there problem interfaces: op declared 2 interfaces same name in 2 separate packages. why casting failed , 6f00 status thrown.

how use shareable interface:

1.declare shared interface public in server-side package:

package com.test.mypackage.a; public interface sharedobject extends shareable {         public void foo(); }

2.use interface in client code:

package com.test.mypackage.b; import com.test.mypackage.a.sharedobject;  ... sharedobject obj = (sharedobject) jcsystem.getappletshareableinterfaceobject(svraid, (byte)0);
  1. use server applet as library when building client applet.
  2. load server applet cap file first.
  3. then load client applet cap file.

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
