3,795 PointsThere are 2 errors here. First one is the "console.readline. Remember camelcase. its supposed to be "console.readLine" Second one is "Console.printf" printf is not a static method in "Console", it is a method in you "console" object. So you need a lowercase "C" in console, not a capital one.
import java.io.Console;
public class Name {
public static void main(String[] args) {
Console console = System.console();
//"console.readLine()" NOT "console.readline()". Remember camelCase.
String firstName = console.readLine("What is your name? ");
//"console.printf()" NOT "Console.printf()". printf is not a static method.
console.printf("Hello, my name is %s\n", firstName);
}
}
Hope this helps you out.

3,795 PointsOk, i have reviewed that challenge and i see that you have gone a little overboard. Read the simple instructions and to the challenge task by task:
First: "Make a String variable named "firstName" and set it equal to your name:
String firstName = "Sudipta";
Second: use the "printf" method on your console object to print "<YOUR NAME> can code in Java!"
//the console object has already been made, the comment on top of Name.java say so. So it is ready to be used.
console.printf("%s can code in Java!", firstName);
//This will also pass the third task.
Read the challenges and do them one step at the time :-)

201 PointsJavaTester.java:126: error: illegal start of expression import java.io.Console; ^ JavaTester.java:126: error: not a statement import java.io.Console;
JavaTester.java:128: error: illegal start of expression public class Name { ^ 3 errors

3,795 PointsThe errors are at line 126 and 127. Are you doing this in a new java-file or trying to add it to an existing one? The java-filename must be the same as the class that the main method is in. Also, all imports MUST be at the top of the file. Are you doing this in IntelliJ IDE or workspaces?
