What is the correct way to declare a boolean variable in Java?

Question

I have just started learning Java. In the online course I am following, I am asked to try the following code:

String email1 = \"meme@me.coh\";
String email2 = \"         


        

Answer 1

As stated by Levon, this is not mandatory as stated in the docs: http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

This is probably either an habit from other languages that don't guarantee primitive data types default values.
