Is my translate between two language(JS and Java) correct?

Please someone tell me what’s wrong with my code.
I translate the code from JavaScript to Java, but I think there must be something problem in it, because it doesn’t work as expected.
BTW, I am not good at JavaScript, if you can tell me what’s wrong with my code in Java,
that’s awesome

Tips: the code following is a certain encrypt method
