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

I am so sorry, I tried several times but my answer turns out "Bummer!" What does this task ask me to do?

I am so sorry, I tried several times but my answer turns out "Bummer!" What does this task ask me to do? I made this string, "string firstName = "Min"; I am sure that this work is correct. I don't know what 'a compiler error' means. What do I need to add ? I appreciate it.

Name.java
// I have setup a java.io.Console object for you named consoles
string firstName = "Min" ;

Hello Min,

Pay attention to the variable type you are declaring, its case sensitive.

In fact, string does not exist, String does

String firstName = "Min" ;

Oh I see. But one more question. When I type "console.printf" , It didn't matter if I started with lowercase. But in case of "String", does it matter? Because string does not exist? Is it explained just like that? Thanks in advance!

When I type "console.printf" , It didn't matter if I started with lowercase

it matters, depends how you have declared your console object, remember that is java is case sensitive.

The following code will work:

Console console; //declaration, your Console object is named console
console = System.console(); //definition
console.printf("Hello !");

Console (upper case C) - is the class

console - is the name you are giving to your object.

so, to use properly your object, the syntax is:

<object_name>.<method>
console.printf()

this instead, will not work:

Console objConsole; //declaration
objConsole = System.console(); //definition
objconsole.printf("Hello !"); // ERROR: we are trying to use objconsole, but does not exist ! (c should be UpperCase)

You are so perfect
