Symbols

I believe that the java basics course is the first course for java on treehouse. I see you're on Strings and variables. Do you have any specific questions about some of the symbols and special characters you've used thus far?

In an attempt to answer your broad question, just remember, String literal values must be placed inside of " ". Any variable you declare in java will end in an ;. And \n is referred to as a String modifier, there are quite a few of them, but what the \n modifier does, is it creates a new line, wherever you place it inside of your print statement.

String helloWorld = "Hello World";  //helloWorld is the variable name, it's of type String, and the assigned value is "Hello World".  And since it's a variable it ends in a semi-colon.

System.out.println("Hello \n World");  //If I didn't use \n, The output would be "Hello World" on one line, instead of two.

OUTPUT FOR PRINTLN STATEMENT

Hello
World

I hope this clears some stuff up for you, let me know if you still have questions.

Don't get discouraged if you come across some material or code that you don't understand right away. The best way to fully understand these concepts is to practice with them, and see if you can use them in a simple way.
