Hi there! so in this code challenge area you actually do not need to put in all of the "boiler plate" portions of this code. This would be the public static void main line and setting up the console object. So for this it is only requiring:

String firstName="shobha";
System.out.println("Hello this is ", firstName);

But there is an issue here, you cannot use println with formatted strings, you need printf. And we can use %s to represent the string as such:

System.out.printf("Hello this is %s", firstName);

For the purposes of this code challenge they have already setup a console object, so to reduce the code a little we can instead use:

console.printf("Hello this is %s", firstName);

Mind you in effect this is the same thing as System.out.printf, just a little cleaner looking!

Happy coding!

Hello Jeevana,

You have two bugs here in your code:

1) Declaring your Console object. Console obj = new Console(); //supposed to be System.console();

2) Printing your first name. System.out.println("Hello this is ", firstName); //supposed to be "System.out.printf("Hello this is ", firstName);"

Please modify your code by fixing these two bugs and it will work, try it: public class JavaDemo { public static void main(String[] args) { Console obj = System.console(); String firstName="shobha"; System.out.printf("Hello this is ", firstName); } }
