Applet logic error

[LogicWavelength]

I am having a terrible time figuring out my logic error. The program is supposed to test if the login info matches what was entered... but for some reason, no matter what I enter it says it's successful... Help!

if (success=true)

That's why it is not only redundant but a very bad practice to compare a boolean to true (or false). I guess you intended to write

if (success==true)

but what you have there is an assignment, so instead of checking if success is true you are making it true. Use this instead:

if (success)

Also, shouldn't there be a break after you change success to true in the loop?

[ProgramThis]

And of course if you ARE going to use the terrible practice of comparing variables like that, or if you are comparing int's maybe, you should always place the variable on the right hand side so that you don't do what you did.

if(true == success)

This will throw an error if you only place one equals sign in there.

if(5 == x)

Things like that.
