Java Java Basics Getting Started with Java Strings, Variables, and Formatting

print your own name with printf. ErrorMessage: Check the spelling of your argument to the printf method. Make sure it

Call the printf method on the console object and make it write out "<YOUR NAME> can code in Java!"

String firstName = "Lajos"; console.printf("Hello name is %s\n", firstName);

or

console.printf("<Lajos>");

or console.printf("Lajos");

Bummer! Check the spelling of your argument to the printf method. Make sure it is printing out what the instructions are asking for.

// I have setup a java.io.Console object for you named console
String firstName = "Lajos";
console.printf("Lajos");

Hi Lajos,

You're not printing out the value of the variable. You need to create a string that includes the first name variable and some text. To do this you need to include the value in your printf method.

This is how it works.

// I have setup a java.io.Console object for you named console
String firstName = "Lajos";
console.printf("%s can code in Java!", firstName);

So first of all you declare a variable with the String data type as you did before. So your name is the value of that variable.

Then you use the conssoles printf method to display that value with the rest of your string. The way you pass in your name as part of the string is with something called a format specifier. You match the value with the name of the vatriable like it is a function argument.

console.printf("%s can code in Java!", firstName);

Hope this helps :)

Thank you.
