Try to use .equals instead of "==".

First you have to install a jdk, i would recommend to use an IDE like Intellij Idea or Eclipse for development.

== compares the objects, not they're values

== checks if the variables reference the same object. .equals checks if the objects are similar, such as if the data they contain are identical. to be more technical, == checks if the memory address of two variables are the same. if they are, they must be referencing the same object which is why == doesn't work. the addresses of the two strings are different
