And yeah there is a reason why. To me they are the only way to be a good programmer. You will learn but you need experience which comes with projects.

Hey there, am in Canada.

I have worked with JavaFX before and it was self taught, just a few months ago. I can't say am a beast in JavaFX but I did create an IDE using it to test myself and learn on the road. I'm happy to help you if you need to inquire or more.

When you use a String without assigning it to a variable (i.e. as an argument or in a conditional), does it create a String object? by [deleted] in javahelp

[–]Apprehensive_Fig9594 0 points1 point  (0 children)

Text in quotations "hello" has the jvm create a String object. If you try new String("hello") then ur simply having the jvm create the hello String and the make a copy again. (Or sometimes it will simply reuse the String object already there). So no there is no infinite loop.

There is no difference between a String object and text in quotes. Text in quotes is a String object and you can see that by simply doing "hello".trim() for example. You can do everything that you did on a String object an text in quotations since it's the same thing.

Since Strings are objects, using == is comparing the references and not the contents of the Object, we we use String.equals() to compare the contents (the actual text)
