  1. Define a string variable named firstName that stores your name. Set the value to your name.

    String firstName = "Sama";
    

    firstName is the name of the String variable. The value it stores is "Sama".

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

    System.out.printf("Sama can code in Java!");
    

    printf is a System.out method that writes to the console. You can use formats to print stuff. The above just prints a line. Below we use "%s" to print your name. You can do the same printing digits with %d and you'll also see %n which means a new line.

  3. Now replace <YOUR NAME> in the console.printf expression with the firstName variable using the string formatter.

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