In computer field- nothing is secure , still but u should try to bother to someone who trying to break something!!!

Not long ago writing a Java Swing desktop application gained a bit of popularity but it's getting a bit outdated now.I think you're just pontificating aimlessly here. How long ago? How much popularity? Outdated how? Since when? By what?
If code security is really important and you couldn't find any other way to secure your code in Java, consider writing your code in C++ maybe?Speaking of outdated. The world these days is moving towards SaS: Software as a Service; albeit at a glacial pace.
