Problem With RSA Interface

[Floetic]

Problem is that the result is not showing in the actual output window of the interface, what is causing this?


All Im getting in the general output of JCreator is this:

Plaintext:
Plaintext:
Plaintext:
Plaintext:
Plaintext:
Plaintext:
Plaintext:

This repeats depending on how many times Ive clicked the Run button.


Thanks.

Correct me if I am wrong, but I dont see anything ever set to your plainText array. It is initialized once, and thats it. And while default value for char is the null character '\u0000', could it be that there simply just is nothing to print out.

It would really help when trying to read your code if you followed the Java naming conventions (variable names start with a lowercase letter).

Programs must be written for people to read, and only incidentally for machines to execute...
