Yes, Java is harder than html. It is also much more powerful and can be very fun. It can also feel very inefficient when you are starting out. ;)

In the challenge you are working on here, they are asking you to use the console object with the printf method in order to print out your name. As jungkeekim said, in Java you can print something with the System.out.print() method, but in this challenge they want you to use the console.printf() method. So, it would look like this:

console.printf(firstName);

They then want you to concatenate strings in the second challenge, which is done like this:

console.printf(firstName + " I am concatenating!");

To format Strings, remember: 

String favoriteFood = "cookies";
console.printf(String.format("I like %s for breakfast", favoriteFood));

In the third example above, keep a special eye on the two parantheses at the end, you must have those or you will get a compiler error. Java is very strict about these things, which is a good thing usually, but can be frustrating. When you become a real Java developer, you will be working with programs called IDE's that correct your silly mistakes for you, kind of like Microsoft Word. ;)

What error are you getting? In this challenge you do not need the public class "solomon", that is an incorrect way of declaring a class and is probably the reason for the errors. When you have removed the public class "solomon" Make sure you have it exactly right, the challenge checker is very picky:

String firstName = "Solomon";

console.printf(firstName + " is writing Java!");
//will print "Solomon is writing Java!"

Notice the space after the first quotation mark in the phrase " is writing Java!". You need that space - (again, the challenge checker is very picky).

console.printf(String.format("%s is writing Java!", firstName));
//will print "Solomon is writing Java!"
